Customer Ratings & Reviews

I played on Razer mice before (old Death Adder and Taipan) and I was looking for an update because I was having tracking issues with the Taipan. This mouse is ergonomic, has the features you want, and has some customization to the weight distribution. The unibody configuration makes for a very comfortable mouse with rubber grips in the right places. This is hands down the best mouse on the market, but you don't have to take it just from me.

This mouse allows you to customize the scroll wheel, dpi settings, change dpi on the fly, add weights, has a sniper button, adjust the gaming surface in the software, and much more. Works great.

First higher end mouse I have ever had and will be that way for a long time. Weight is great, especially with the available weight add ons. Love the buttons on the side s of it for games and just desktop use. Great mouse!

I consider this mouse to be the best on the market. I recommend it over $150+ mouses, including more expensive Logitech mouses. It looks great, feel great, performs great, and is completely customizable in regards to lighting, button mapping, and mouse scroll.

Purchased for gaming and am not disappointed, lots of options and your can customize the configuration a lot. Includes additional weights and has a nice feel all-around. I like being about to quickly adjust the DPI settings up or down, plus the slow override too.

I’ve tried several razer mouses like the death adder elite, none of those compare and were even more expensive. This mouse feels perfect and has even improved my accuracy in games after balancing it with the included weights. Looks slick and not too flashy

Very comfortable for my hand and it really has improved my gaming experience by a lot.

I like this mouse alot. I have slightly bigger hands and this mouse feels a little small in my hands but overall its still really good. Good customization, smooth and easy to use. I would buy it again.

Everything about this mouse is perfect. Customizable rgb lighting. High speed tracking. Customizable buttons. The only complaint I have is that while playing the scroll wheel will roll and switch my weapons but it is expected with an infinite scroll wheel that is as buttery as this.

This mouse is amazing for FPS, the dpi change is great for when changing from vehicles to foot as well.

Love the feel in my hand and the different profiles you can set up and manage easily.

I like the options the mouse provides. You can change DPI on the fly, and program the buttons for other functions based on profile, or based on game using the Logitech software. The lights are fun, and the weights don't seem to make a difference for me. Though the container provided for the weights is a nice touch. I really like the braided cord, it's flexible, and lays flat on the desk. The mouse tracks perfectly and has gotten me addicted to KB/Mouse control over controller.

Great mouse, might be the best mouse. The ability to adjust the weight of the mouse makes it very nice to use. Also the adjustable DPI, let me tell you about the adjustable DPI. Well the DPI, you can adjust it. It's very adjustable. To quote a famous celebrity, it's very nice.

Great ergonomics, and a great feel to this mouse. I really do enjoy using this mouse.

Ergonomically sensitive, the mouse feels good to use and is appropriately responsive.

First off, I have big hands. So I was looking for an affordable mouse that didn't feel puny. Upon opening the box, I put all the weights in, but I could've used more weight myself. The mouse glows with a changing range of colors and glides easily. The sensitivity is adequate. My only complaint is that the metallic scroll wheel doesn't feel as responsive as a rubberized one, so it slips a bit on my hands. Overall I'll give 4 stars because it feels and acts better than an average mouse.

I had the 502 standard then moved to this. The lighting makes the original 502 that much better!

My daughter loves this mouse. She says it has more controls and is more responsive.

-Pros- Plentiful programmable buttons Fantastic tracking Arguably the best scroll wheel Infinite scroll button to allow endless scrolling with scroll wheel Attractive design Adjustable weights -Cons- Side grips Weight Comfort If you do any research on gaming mice then you will already know that this mouse is at the top or close to just about every reviewers list and on the surface it isn't hard to see why. Enough buttons to satisfy an MMO gamer, great button placement for FPS and MOBA gamers. It is also useful for those in the professional field, the infinite scroll option allows you to scan through documents and code much faster. The option of adjustable weights is a pro, but for me it became a con. The mouse is heavy without any weights added to it which was a pretty big con for me because I am used to light mice and it was confusing since this is not a wireless mouse. Most mice that I have tested in the gaming market are light without weights added, wireless mice being the only types to have a heavy weight to them. I believe the heavy weight is contributed to the scroll wheel that seems to be made of heavy metal, I said the scroll wheel is arguably the best because it feels incredible and the infinite scroll option is a huge plus, but I believe the material gives the overall weight of the mouse more weight which is a big con for me. The rubber feeling side grips seem to be gaining traction in the gaming community unfortunately with reviewers complaining that it should be a standard option. I absolutely hate rubberized side grips or any type of grips for that matter. My skin is very oily and I participate in long gaming sessions with Mice that have no side grips and never drop or loose control of the mouse, but most seem to find side grips a must so take my displeasure with side grips with a grain of salt. The grips tend to dig into my skin and create discomfort for me personally. The button placement is well done, but I found the buttons themselves to be a bit too rigid for my grip style. The side buttons have a sharp angle to them and depending on your grip style your thumb will hit that angle instead of the intended area. I would always hit that angle which was a pretty big annoyance. I use the G400s as my daily driver and it has rounded soft touch buttons which give a much more comfortable feel. I would loved to of seen them put these or something similar into the 502. I wanted to give this mouse 2 stars instead of 3, but I feel my complaints don't seem to carry over to most and this mouse really is amazing, but I can't use it because of all the uncomfortable things I listed above. Spending extra money on a gaming peripheral should get you everything you are after and then some, so if you are in the same boat as me then don't just settle and continue with me to look for the ideal mouse.

Fantastic mouse for gamers. The mouse has 3 programable settings that you can access and customize to fit your gamning needs. The mouse is a thinner profile and longer than most of the gaming mice out there and felt it countoured to my hands perfectly. I highly recommend this item and have actually had a friend purchase this and is very satisfied with it as well. I also haven't had any technical issues with it either works perfectly.
