First of all, it's important to note that this is a review of the Razer Basilisk X mouse, not the Razer Basilisk Ultimate which is a vastly improved version of the mouse. Most of the reviews are for the Basilisk Ultimate for some reason, but with a picture and the one you order on this page, you'll get a battery-powered Razer Basilisk X. TL; DR: I've been using this mouse for office use for a month. Great price for what you get. Feels good in hand with traditional grips (claw, palm, fingertip), responsive pressure, nice scrolling, glides well on mouse pads, good for gaming, really good battery life. I've only used wired mice so far. I wanted a wireless office mouse because my desk was getting smaller. I also now share a desk and the cables come from our headsets, keyboards, desk decorations etc. To put it mildly I wanted something cheap but something I can count on with decent quality for the price. After extensive research, I decided on Logitech or Razer. When I finally saw the Basilisk X, I loved the look and feel. The more I thought about it, the more I fell in love with him. I was skeptical as I've never used a wireless mouse before. However, below are my thoughts after a month of use regarding the mouse and why I think this mouse deserves five stars for the price. For starters, the price drops to $59.99 at the time of writing this review. Even after paying full price I felt I was getting an excellent quality mouse. Below are some more features of it. First, after receiving the mouse, you will receive detailed setup instructions. It's a nice touch, as it can be difficult to casually figure out where the battery compartment and USB drive are. The lid lifts well, but is difficult to put back on. Ultimately though, it has a good USB drive and battery bay. This mouse is powered by one AA battery inserted in the mouse. The mouse is very light and easy to move. The mouse construction feels decent for the price and feels solid. The overall look of the matte black mouse with some glossy details and highlights is personal preference, but I like its simple, unlit look. Overall, this mouse feels good in the hand. I've used it in several different shots to try how it will feel. I used claw, palm and fingertip, the most common pens I could think of. I felt relatively comfortable every time I used each grip. The mouse fits my average hands fairly well. I personally use a hybrid palm/claw grip, in the sense that my palm covers most of the mouse but my fingers are slightly elevated. It's a little less comfortable for this type of grip, but you can still feel comfortable using a mouse. Based on my usage, the mouse is primarily intended to be gripped with the palm of the hand, but that shouldn't disregard other grips, at least the mouse attempt. These are way better than the mice the office provides me, believe me. As with other parts of the mouse, like buttons and scroll wheels, I like the responsiveness of the mouse buttons. Also, my fingers don't hang over the edge even when using my palm, which I personally like. I like the scroll wheel better because it doesn't take too much effort to move it up or down, but it snaps into place easily. It's relatively easy to scroll quickly, but not as easy as the Logitech mouse my friend let me have for a moment (more on that later). Three other keys can be used: one under the scroll wheel and two next to the thumb. One complaint I've had with some other mice I've used, including Steelseries and (on some mice) Corsair, was accidentally pressing that sensitivity button under the scroll wheel. Well, I can safely say that I've never accidentally pressed the sensitivity button. However, being clumsy, I occasionally accidentally press the two buttons on the side of the mouse. However, when I have a mouse with buttons in those places, I always accidentally click it, regardless of the mouse, so I can't fault it. The buttons on the side protrude a bit more than I usually see on other mice, but they don't get in the way, especially the sensitivity button. It's flush with the two buttons to press. Overall, using the included thumb rest gives you fairly easy access to the thumb buttons. I can say that it has a simpler design that some would prefer to the many buttons. The back cover for the battery and USB holder has never accidentally come off and I had no problems reassembling it. I'd say if you have average hands this mouse would probably be for you, but it still works well for someone like me who has slightly large hands. In order to move quickly, I will now explain how the mouse works when moving, and then dive into the game with the mouse. In general, on a good quality mouse pad, the mouse glides very smoothly over the surface and is easy to calibrate. All, what you have to do to calibrate it for the surface you are on, software or not, is hold down the button just below the scroll wheel for a few seconds and then it will be for the surface it is on located, calibrated and optimized. It never stuck to anything and runs fairly smoothly, if a bit quickly. Otherwise, it dances very elegantly across the surface. Finally, what I'm most looking forward to is the games. This is a gaming mouse, so how does it work in games? Well after spending a few days playing with this mouse instead of my regular mouse, the Corsair Nightsword, I can say it's not that bad. Of course, I always recommend a wired mouse for certain types of games, but if you want something wireless where latency and response time aren't as important, this could be the mouse for you. I've spent time playing Destiny 2, Call of Duty Modern Warfare, and even the rhythm game osu! The lag is a bit more noticeable here, but still not too bad. It was easy to be precise, although of course it was an adjustment. After playing with him for a few days, I was able to play at about my usual level, which isn't great to start with. Needless to say, it works with certain types of games, but for the FPS genre or games that are sensitive to response time, you may notice a lag. Sure you could probably get used to it but you might get better results with a high-end mouse or a wired mouse. This doesn't mean the mouse didn't work, it worked very well. I'm sure if I was playing Dota 2, RTS or MMO this mouse would still be usable, but I understand that you may need additional keyboard shortcuts if you want to play RTS or MMO. In summary we can say that it does its job. Finally battery life. I went into it in disbelief. I saw a review that said it repeatedly drained batteries for a week and a half. So I was a little skeptical about Razer's claim of 285 hours of ultra-fast WiFi. However, I had an Energizer battery that came with the mouse (thanks Razer!), and it lasted a month. Keep in mind this was for office use and I have a desk partner. As soon as she leaves, I will immediately take her place (she also likes mice, by the way). She works eight hours five days a week and I work six hours four days a week. I realized that calculating this mouse's approximate battery usage using only these numbers would be inaccurate or maybe a bit skewed, so I'll just leave this as a mere statistic of how often we use it to confirm battery life. Also, only one AA battery. At least, you can pay for some batteries, but I really can't complain about the battery life I get from them. I hope that if you are considering purchasing this mouse, outlined my months of experience with this mouse in relation to office use. Take the gaming section with some skepticism as I haven't used it in a couple of days. And again, this article is mostly opinion but I've tried to keep it open to show some cons but mostly pros because I like it. Thanks again! Since I haven't used it for a few days.
