I have always strayed away from wireless mice. Mainly because of the bad experiences when they first hit the market. Razer has proven that it has come a long way.It just feels good in the hand. It molds to your hand for a comfortable grip, leading to a more relaxed grip.The RGB is a great touch for those that enjoy RGB lighting. It is at the perfect brightness to not distract, but give a nice ambiance to your setup.The adjustable scroll wheel was more helpful that I thought it would be. It goes from free wheeling to a single click with the press of a button. Depending on your game, it could be very helpful. I generally use the freewheeling for scrolling webpages, and swap to single for gaming.The battery life is excellent. In over a month of use, not once did it die mid game on me. This is due to the automatic downscaling when the battery is getting low. As a casual gamer, I never really noticed. On a competitive gaming field, this may be more noticeable, but chances are you are charging the mouse any time you are not at the computer. My main complaint is the ability to wirelessly charge the mouse, but having to buy extras to be able to do so. It's like DLC for a mouse. You need to spend an additional $20 to buy the wireless charging puck, and then buy the wireless charger on top of that. I am not sure if a "wireless charging mousepad" will work with this, but not including at least the wireless puck is a lame move.I would have preferred a button to increase and decrease the DPI on the fly instead of having to cycle through all the DPI settings. I did find in razers defense that the razer app allows you to set custom DPI settings on the mouse, so once you find what you like, you can add only those settings. I found myself only using 2 different DPI settings, so switching was easy.Overall this is a great mouse for both competitive and casual gamers alike. The app gives a lot of control over the mouse. It is a bit pricey, but you can tell that there was a lot of thought and time put into the mouse development.
