Nice, quiet and durable mouse
Color: Black and Gold
After trying several mice, I purchased one of these. It is small and very quiet. Since I spend many hours a day at a computer that can be rough on mice. I have since purchased more of these. It will take the average user quite a while to wear one out. And they are inexpensive.

Incredible Precision and Comfort for Gaming and Design
Size: Standard, Size: Standard
After using this mouse for a couple of weeks, it just confirmed again why I’m such a fan of Razer products. The ergonomics are excellent, and it feels surprisingly lightweight considering it uses a AA battery. The low latency with Hyperspeed technology is fantastic, and the sensor precision is seriously impressive. I spend hours playing Fortnite and the connection has been completely reliable the whole time. I’m also a designer, so I need accuracy for detailed work in Illustrator, and this mouse has performed perfectly for both gaming and professional use. Definitely one of the best wireless mice I’ve used.

Excellent Wireless Mouse with Great Performance
Size: Standard
The Razer Basilisk V3 X HyperSpeed is an outstanding gaming mouse. The wireless connection is fast and reliable with no noticeable lag, and the mechanical switches feel crisp and responsive. It’s comfortable to hold even during long sessions, and the customizable buttons add a lot of flexibility for both gaming and productivity. Battery life is impressive, and overall it delivers great performance for the price.

Great mid range mouse option
Size: Standard
My previous mice include the Razer Deathadder V2, Razer Basilisk V2 X Hyperspeed, and the Logitech Pro X Superlight.
This is easily the most comfortable mouse I've used, the contours feel perfect and the extra button the side is well placed and feels like a natural addition. I've personally not found the weight an issue, though it is much heavier that most other mice, even ones that use a AA battery. I do prefer the external battery as I disliked having to plug in my mouse every so often to charge it, something that became much more frequent as the internal battery lost capacity.
The new switches feel excellent, a noticeable improvement from the V2. Performance is good in all areas with the exception of the scroll wheel, which feels like it eats inputs for breakfast lunch and dinner. Basically when scrolling fast the Basilisk V3 seems to skip inputs. My V2 had similar issues and eventually I had to replace it when the scroll wheel started acting haywire and scrolling on its own or backwards. Something to keep an eye on.
Appearance is unremarkable. The new RGB scroll wheel is appreciated, but fairly simple in customization. I have it set to static color but you can have it be reactive to clicking, color cycle, breathing, or a few other options with Razer Synapse.
One small quirk is that if you have auto sleep on, it takes a bit to actually turn back on when using it again. Whereas the Razer Deathadder V2 was near instant in my experience, the Basilisk V3 takes a few seconds to get going, which sounds like nothing but does make a difference when it happens so often.
TL;DR - It's a really good mouse at this price point, good performance and great comfort. Only negative is the scroll wheel and the weight if that matters to you.

Not as good as a 3S, but less expensive. Hopefully better quality switches than the 3S.
Size: Standard
I like this mouse, but it could be better. I purchased it to replace a Logitech MX-Master 3S, which is a great mouse except the microswitch for the left button stopped being reliable after less than three years. While that's a reasonable life for some users, perhaps, it seemed inadequate to me. My use case is general pc use for searching the web, writing emails, and managing finances. The Logitech wasn't used every day.
The 3S has a higher palm hump, which the Basilisk lacks and I really prefer. The Basilisk is similar in overall size to the 3S, so for the most part it fits my hand sufficiently well. Hump size is the main downside to the Basilisk. That, plus the battery is not rechargeable. What, in 2026?! But I've adapted to it, and battery life so far has been very good. It has the combo BT + 2.4 gHz connectivity with a dongle. Both choices work very well and reliably. I like the center wheel size and action a lot. I like the slip pads on the bottom of the mouse. It has a very handy and perfectly responsive third thumb button that I don't currently use but gamers may find it useful. Only time will tell if Razer's microswitch quality is more durable, reliable, and longer lived than the crap switches Logitech put into the otherwise very good 3S. I have used the Basilisk about two months at the time of this review.
