⭐️⭐️⭐️⭐️⭐️ Amazing Mouse – Worth Every Penny!
I recently upgraded to the Razer Basilisk V3, and I couldn’t be happier! The ergonomics are perfect, making it super comfortable for long gaming sessions. The customizable buttons are a game-changer, and the Hyperscroll wheel is insanely smooth. The RGB lighting looks incredible, and the performance is top-notch with its 26K DPI sensor.Whether for gaming or everyday use, this mouse is responsive, precise, and feels premium. Definitely worth the price! If you’re considering an upgrade, get this mouse—you won’t regret it!

Great for both work and play
A fantastic piece of kit - whether you need a premium quality mouse for work or fun. Plug-and-play to get going easily, or spend hours for customising the colour patterns, button assignments, sensitivity or other features. I found it fitting perfectly into my medium-sized palm, and surprisingly ergonomic even after using vertical mice in the past. If I'm really picky - I can point to the fact that the battery is "only" good for some 12-14 hours of gaming at the highest polling rates, but in real-life if you don't max the resolution and sensitivity it'll work wirelessly for 5 work days in a row.I'd certainly buy one again.

Precision and Style – This Mouse Delivers!
I've been using SteelSeries products for years and I recently picked up this Razer Basilisk V3 Pro gaming mouse, and it’s been a fantastic upgrade for my setup! The ergonomic design fits perfectly in my hand, making long gaming sessions comfortable. The RGB lighting is a nice touch, adding a vibrant glow to my desk while being fully customizable. The mouse is incredibly responsive, with smooth tracking and precise clicks that have improved my performance in fast-paced games. I also appreciate the programmable buttons, which let me tailor it to my needs for both gaming and productivity. If you’re looking for a high-quality gaming mouse that combines style, comfort, and performance, this Razer mouse is a must-have. Absolutely love it!

A great mouse but thumb button is annoying (and Mac users be aware)
This is a very nice mouse, and I was sad that it just wasn't the one for me. It feels high quality and ergonomic, the clicks are satisfying without being too loud, and the scroll is very tactile. The DPI options are useful but I found the upper two insanely fast. Unfortunately, I couldn't get used to the button next to the thumb - my thumb was always bumping into it, and if I sat my hand further back then the overall width to my ring finger was too much (I have long, narrow hands). Also, I knew already that the Razer software is not Mac compatible, but didn't realise that OpenRGB doesn't provide support for this particular mouse yet (the Wireless V3 X Hyperspeed). So it's a lot of money for a mouse that isn't super comfortable and I can't change any of the buttons and RGB. Tempted to try the old Basilisk X Hyperspeed which has fewer buttons.

Great alternative to the g502
I bought this mouse as I was looking for an alternative to the g502. I was originally planning on upgrading to the g502 x, but when comparing with this mouse I had noticed that the only real upgrade on the g502 was the switches. This mouse also comes with optical switches and an improved sensor over any current g502 with some pretty nice RGB. The buttons feel okay, not as nice as mechanical switches, but the scroll wheel is absolutely amazing. It fits in the hand in both claw or palm grip and is very comfortable to use. The similar shapes definitely made the transition easier.

Brilliant mouse, comfy to use
I had the wireless basilisk for work for years and have always found it comfortable to use, I’ve had this for probably 6 months at least and it works perfectly fine, syncs with other products wellLight, clicks feel of good quality, don’t get lag as wired, perfect sizing

Amazing gaming mouse
Fits nicely in the palm of the hand. Extra buttons on the side are very responsive. The software is easy to use and make it easy to customise the mouse. The mouse also has nice weight to it making it feel high quality. With heavy use the battery can run out quite quickly. About a week give or take.

The worst RMA experience I have ever had.
This mouse has been lovely. 5 out of 5. Until it broke one day. 14 months or so after purchase, the much loved wheel scroll suddenly lost it's locking mechanism while I was browsing a website. For a >£120 mouse, it is frustrating but I knew it was still under 2 year warranty.Contacted Razer support. 16+ emails, 2 images, 1 PDF, 1 video, 3 printouts, and 1 trip to local FedEx dropoff later... I still have the broken mouse in my hands!This RMA system is just bonkers. I don't think I can buy another Razer product again. Dyson, Logitech, Ninja... all items I have had to claim on warranty in the past 4 years - all smooth experiences. Only Razer cuts like this!Such a shame, it really is a nice mouse. But for the premium you pay, you would expect much better customer care.
