Customer Ratings & Reviews

First time buying a razer or wireless mouse at that.. Glad that it was this one, I got it on sale for about $30 off. The response is really quick, no lag, even on wireless (this mouse can also be plugged in to be wired btw). It’s charge lasts all day for as much as I use it, I have yet to have it run out on me in a given day. I always charge it daily after im done using it. Most likely will buy again in the future when I need more mice.

Very smooth mouse. Nice weight to it. Connects easy. Bought it on sale and saved $70.

Got this mouse after using the mamba elite for a couple years. This mouse is perfect for bigger/wider hands! The mouse clutch button on the side is hard to reach but other than that it is an amazing mouse, also there is ZERO lag!

Was looking for something that would feel the same as a wired mouse for both work and gaming and this mouse delivers it.

Husband loved this mouse, there doesnt seem to be any lag to it and would recommend for the price

This mouse is so smooth and comfortable to keep my hand on all day. And the service with best buy was great!

This is my first time buying a Razer mouse and I have a great experience with it.I like it.

This mouse battery takes a bit to charge for the first time but then will last all day. the mouse is good for large hands and has a nice weight to it. the dock is a bit hard to get the mouse one, it will just take some time.

I'm a longtime Razer fan, I've had my Black Widow Chroma keyboard for five years and never an issue, this mouse is great on response, battery life and everything I'm not a wireless mouse fan but this one is epic!

Bought this on sale primarily for the charging dock. I already have the mouse but without the dock. Mouse works great so when I saw this on sale I scooped it up. I can use the other mouse with my laptop.

Great gaming mouse for its price the RGB on it looks amazing and it glides well on any mouse pad you have

I wouldn't consider myself a hardcore PC gamer, but this mouse is great! The charging dock makes it super convenient and being able to plug the mouse directly into the computer is also super helpful.

I use it for gaming and it works as expected. Kids like the color changing.

I'm very surprised with this mouse. I bought both this and the Logitech G20 anticipating I would wind up with the G20. I was wrong. The Razer Ultimate is comfortable, has a longer lasting battery life, cool lighting, and a much better wheel. The part that convinced me is the ability to adjust the wheel tension. The downside is the pricetag. Overall, it's impressive and a real blow to Logitech in my opinion.

Purchased this for my son as an upgrade. He loves it. It operates great while gaming

Super-fast in its response. Very light touch. Comfortable and attractive.

I bought this mouse and the Razer Viper Ultimate but ending up returning this for one MAJOR reason. The scroll wheel DOES NOT ALWAYS register when you scroll up or down. Let me clarify.... I play first person shooters like Destiny 2. I used the scroll wheel often and I really like that you can adjust the tension of the scroll wheel on the Basilisk Ultimate. HOWEVER, the huge flaw to this design is when you use the scroll wheel it random does not register your scroll. Multiple times I went to switch my weapon and died because it didn't register my scroll up or down even though I did scroll down and it even click (you know how a scroll wheel clicks when you scroll up or down). I tested everything and increased/decreased the tension and it kept happening. REAL BUMMER because other than this one issue, the mouse is PERFECT. But this is a major design flaw. Paying almost $200 for a mouse and then scroll wheel doesn't work properly? My $20 Amazon mouse registers every single time I scroll up or down. Don't buy this. Buy the Razer Viper instead. I have had both and I kept the Viper.

I've been using this mouse mostly for work, but it works great for gaming as well. Lots of customization options. The charging dock is convenient and works great. I've never had any connection problems or any other issues.

better than its next version (EL PRO) it is the same only without all the RGB and even more with the charging dock and for less money

At first I was real hesitant on building a wireless mouse but after seeing the reviews on YouTube I took the chance and brought it. It super smooth and glide across my mat like butter. Super responsive as well. Great buy
