    The mouse itself is great, feels good in hand and looks nice. However, the biggest issue is the left and right mouse buttons. They are so loose right out of the box, and whenever either button is depressed you can feel them move slightly left and right. It’s so distracting in game, and even to the point where it is hard to drag a window around on your desktop.

    I’m not an Apple fan-boy, but I do love my MacBook Pro 14 M1 Pro…just love it. With that in mind, I wanted to flex the mini-LED screen of my beloved with games like CoD, so of course I needed a decent gaming mouse that would be up to the FPS tasks the game would throw at me. Trouble was I didn’t want a USB-A dongle sticking way out of my otherwise puma sleek beauty of a laptop (even more so because in order to use the dongle, I would have to use a USB-A to USB-C adaptor, which would just look ridiculous – COME ON Razer, Logitech, and a host of other manufacturers, why haven’t you yet embraced USB-C 2.4 GHz dongles), which really limits me to two just gaming mouse offerings from the two big boys: Razer and Logitech, that have Bluetooth connectivity onboard. I grabbed this mouse on super sale, and so far I’m pretty happy. It’s not a flagship Razer mouse; it lacks a rechargeable battery, wireless recharging, and even lacks the snappy looking LED lights found on so many gaming mice, which I personally really like…within reason. But this mouse is a bonafide gaming mouse with a DPI and polling rate to match, and equally importantly, this mouse has excellent ergonomics for right-handed people (left click button is higher and at a different angle than the right click, making it incredibly comfortable to use). Sorry left-handed people…though you are in the minority by quite a bit here. Anyway, if you’re looking for an inexpensive, no frills, but effective, dual-connectivity mouse with great ergonomics, I recommend giving this one a go.

    Firstly, one important thing to address is that this is a review for the Razer Basilisk X mouse, not the Razer Basilisk Ultimate, which is the majorly upgraded version of the mouse. Most reviews, for some reason, are of the Basilisk Ultimate, but with the one picture and the one you order on this page, you will be getting the battery powered Razer Basilisk X.

    TL;DR: I used this mouse for a month for office use. Great price for what you get. Feels nice in hand using common grips (claw, palm, fingertip), responsive clicking, nice scrolling, glides well across mouse mats, fair for gaming, really good battery life.

    I have only ever used wired mice. I wanted a wireless mouse for office use because my desk got smaller. I also share a desk now, and wires go everywhere from our headsets, keyboard, desk decorations, etc. To say the least, I wanted something cheap, but something I could still rely on with decent quality for the price. After doing some extensive research, I limited myself down to Logitech or Razer. When I finally laid eyes on the Basilisk X, I liked the look and the features. The more I thought about it, the more I fell in love with it. I was skeptical, as I’ve never used a wireless mouse. However, below are my thoughts after a month’s use regarding the mouse and why I think, for the price, this mouse deserves five stars.

    To start, the price falls at $59.99 at the time of writing this review. Even in paying full price, I felt that I was receiving a great quality mouse. Below are some more specifications of this.

    Firstly, when getting the mouse, you get some detailed instructions regarding how to set it up. This is a nice touch, as trying to offhandedly figure out where the battery compartment and the USB stick is can be difficult. The cover lifts up nicely, but is a little hard to put back on. Ultimately, though, it has a nice compartment for the USB stick and for the battery. This mouse takes one AA battery inserted into the mouse. The weight of the mouse is very light and it’s easily mobile. The build of the mouse feels decent for the price, and seems durable. The look overall of a matte black with some glossy parts and highlights is personal preference, but I do like its simplistic look with no lights on it.

    Overall, the feel of this mouse is nice in the hand. I used it in a few different grips to sample how it would feel. I used claw, palm, and fingertip, the most common grips I could think of. When using each grip, each time, I did feel relatively comfortable. The mouse fits rather well in my medium-large hands. I personally use a hybrid palm and claw grip, in the sense that my palm encompasses a large amount of the mouse, but my fingers are raised slightly. It is a little less comfortable for this type of grip, but you can still feel comfort using the mouse. It seems from my usage the mouse is mostly intended for palm grip, but that shouldn’t discount other grips at least trying the mouse. It’s much better than the mice the office provides me, trust me on that. As for the other parts of the mouse, such as the buttons and scroll wheels, I like the clicky responsiveness of the mouse buttons. Also, my fingers don’t hang over the edge, even when using palm grip, which I personally love. I rather like the scroll wheel because It doesn’t take too much pressure to move it up or down, but locks into place pretty solidly with ease. It is relatively easy to scroll at fast paces, but not seemingly as easy as a Logitech mouse, which my friend allowed me to use for a moment (more on that later). There are three other buttons to be used, one below the scroll wheel, and two next to the thumb. One complaint I had about some other mice I used, including Steelseries and (in some mice) Corsair, involved me accidentally pressing this sensitivity button below the scroll wheel. Well, I can safely say I’ve never had an accidental press of the sensitivity button. Since I am clumsy, though, I do accidentally press the two buttons on the side of the mouse every so often. However, whenever I have a mouse that has buttons in those places, I always click them on accident, no matter the mouse, so I cannot fault it for that. The buttons on the side stick out a little more than I usually see on other mice, but they don’t get in the way, especially the sensitivity button. It sits flush with the two buttons used to click. Overall, you get pretty easy access to the thumb buttons when using the provided thumb rest as well. I can say it has a more simplistic design, which some will favor over multiple buttons. The cover in the back for the battery and USB holder have never come off accidentally for me, and I haven’t had issues otherwise with the build. I’d say if you have medium hands, this would probably be the mouse for you, but with someone like me who has hands that are somewhat large, it works well still.

    Moving along swiftly, I’ll now cover how the mouse performs when moving it around, and then dive into gaming with the mouse. Overall, on a decent quality mouse mat, the mouse glides really smoothly across the surface and calibrates easy. All you have to do to calibrate it to the surface you’re on, software or not, is hold down the button just below the scroll wheel for a few seconds, and then it is calibrated and optimized for the surface it’s on. It’s never caught itself on anything and feels pretty smooth, albeit a little bit speedy. Otherwise, it’s very elegant in its dance across a surface.

    Finally, the point that I’ve been looking forward to most, which is gaming. This is a gaming mouse so, after all, how does it perform for gaming? Well, after spending a few days gaming with this mouse instead of my regular mouse, a Corsair Nightsword, I can say it isn’t too bad. Granted, I will always recommend a wired mouse for certain types of games, but if you want something wireless where delay and response time are not as important, this could be a great mouse for you. I spent time playing Destiny 2, Call of Duty Modern Warfare, and even the rhythm game osu! The delay is a little more noticeable here, but it is still not that bad. It was easy to be precise, though, of course, it was an adjustment. After playing with it a few days, I was able to play at around my normal level, which isn’t that good to begin with. Needless to say, it does its job with certain types of games, but for the FPS genre or reaction time sensitive games, you might notice the delay. Granted, you could probably get used to it, but you might get better results from a higher tier mouse or from a wired one. That’s not to say that the mouse didn’t perform, because it very well did. I’m sure that if I played Dota 2, an RTS, or an MMO, that this mouse would still be viable, but from what I understand, you may want some more keybinds readily accessible if you’re going to play an RTS or MMO. To wrap it up, though, it does its job.

    Lastly, battery life. I went into this with a grain of salt. I saw a review saying it ate batteries in the matter of a week and a half repeatedly, so for Razer to claim up to 285 hours of hyperspeed wireless, I was a bit skeptical. However, I had one Energizer battery that came with the mouse (thanks Razer!) and it lasted a full month. Keep in mind, this was for office use, and I have a desk partner. As soon as she leaves, I am right there to take over her station (she loves the mouse too by the way). She works eight hour shifts five days a week, while I work six hour days, four days a week. I figured calculating out this mouse’s approximate battery usage using just these numbers would be inaccurate or possibly a bit skewed, so I’ll just leave it at the pure statistics of how often we use it to prove the battery life. Also, only one AA battery. To say the least, you may pay for some batteries, but I really can’t complain with the battery life I get from it.

    So, if you’ve stuck around this long, I want to thank you for sticking around, and I hope that if you’re considering buying this mouse, I have laid out what my experience with this mouse was for a month regarding office usage. Take the gaming section with a small grain of salt as I didn’t use it for more than a couple days. And again, this article is mostly opinion, but I tried to keep it open to show some cons, but mostly pros for why I like it. Thanks again!

    While the mouse looks and feels good, I’m very disappointed in Razer. They promote how amazing their “Hyperspeed Connection” is but it’s god awful. For the last year, I’ve been using this cheap $20 wireless mouse from some Chinese company for work and I’ve never had a connection with it. You’d imagine this $80 mouse with their “Hyperspeed Connection” to be even better right? Well, wrong. I consistently have issues with the mouse freezing on me and/or disconnecting whether I’m on Hyperspeed or Bluetooth mode.

    The battery life isn’t horrible but it isn’t amazing either. I really wish they would have gone with a USB charger instead of batteries but in the end, it’s not a huge deal. I had to replace the battery once in about a month of fairly heavy usage which I can’t complain about.

    Now, the main issue is that the right-click button keeps glitching out and makes it nearly impossible to use it in an FPS game like Call of Duty.

    I’ve reached out to Razer last week regarding this and I’ve yet to get an answer from them. Even if they’re willing to replace this one, I definitely do not plan on purchasing any of their wireless products again.

    This is one of the least reliable devices I’ve ever owned, which is a shame considering how great it feels in the hand.

    Several times a day, whether on bluetooth or wireless connection, the mouse will randomly lose power and disconnect. Removal of the battery, resetting it, switching between connection modes does not fix this. What does? I have no idea. It randomly comes back to life, sometimes after 30 seconds, sometimes after 10 minutes.

    Absolutely unacceptable product quality given the price point. I’ve always heard about Razer’s QC issues but this is absolutely unbelievable for a relatively simple device.

  6. Eric Kauffmann

    Decidí comprar este mouse por el precio accesible, pero ya probándolo no me gustó el sonido de los clicks,se escuchan fuertes, graves y de baja calidad. De igual forma este mouse no es tan sensible como el g502, probándolo detalladamente simplemente se siente movimientos toscos del puntero en la pantalla, ni ajustándolo con su programa de raez r queda bien, no lo recomiendo, mejor me voy con logitech.

  7. Jason P. Williams

    Quite possibly the best mouse I’ve ever owned. Pairing was a snap. I generally use the bluetooth to connect so that I don’t have to tie up a USB port. It is really comfortable in the hand, with a great distance between the left and right mouse buttons. The thumbrest on the right side is really comfortable. The on-the-fly adjustments to sensitivity are great (although I don’t know who would use the highest levels, because they are REALLY sensitive – a little flick sends the cursor across the whole screen). You can also set your own custom sensitivities in the Synapse software. The extra two buttons on the side are programmable to bind any keyboard function you want – it’s a nice mid-ground between no extra buttons and a hundred extra buttons some gaming mice have.

    Overall, I definitely recommend for the casual gamer/user.

  8. Luis A. Delgado Lisiñska

    So far I have found it to be an excellent mouse, considering that I come from using other mice from ryzer, but not dedicated to games, previously I used a razer atheris for the laptop and a razer deathadder for the desktop PC, the DPI cannot be compared with the basilisk, this one has 16000 DPI it took me a few days to get used to it, the configuration through the dongle is very easy, it’s just plug and play, the system takes care of downloading what is needed for the device to work, referring to the razer software, I’m not a big fan, the customization of the buttons for other uses is interesting, but I’ve never seen it useful, you can also configure it to work via bluetooth, which is also very easy and does not require the use of the dongle, this can be stored inside the mouse, the OS in my case Windows gives an approximate percentage of the battery status, the same does the razer app, another note is that the battery life is longer if used via bluetooth, but I don’t know taking into account that the super-fast response of the mouse will be compromised, in summary it is a robust mouse, but light, the construction material feels better, not like the deathadder, which feels cheaper, by the way this mouse works with only one battery, not like the atheris that requires two.

    Ya tenía otros mouse inalámbricos pero compre este por estar en oferta. La verdad no es el más ligero y es algo grande pero a mi me resulta cómodo de usar así que lo veo como buena opción para un uso cotidiano y no sólo gaming. Por funcionalidad y precio lo veo como una alternativa al mouse g305 de logitech, los dos son inalámbricos y con buena duración de batería siendo el basilisk más grande, más pesado, con mejor ergonomía y se siente un tanto de mejor calidad de construcción. En cuanto a gaming el sensor es muy bueno e igual de responsivo que un mouse con cable siendo más práctico y cómodo al no tener cable, por lo mismo en un mouse que también recomendaría para usar con una laptop.
