Summary: For anyone who games and needs wireless, this is my recommendation. If you don't need wireless, this has a wired option but you can save some money by buying the deathadder, a wired only model of this mouse. I did a full overview of this mouse on my youtube channel, and my final thoughts is at about 5 minutes in.
Summary: I received the product quickly, there was nothing wrong or broken when I opened it and the drivers installed correctly and easily. It takes a little getting used to just like any mouse but it the response time is great and I love the on-the-fly DPI adjustment. I think I will be using this mouse for a long time to come.
I've owned a lot of gaming mice, this seemeing is the end.

Summary: I chose this mouse because razer makes top quality gaming mice and I know what to look for in quality mice. I originally bought this for gaming and to be honest the 6400 dpi is a huge fancy number to make you think its amazing and super necessary. You won't ever have the sensitivity up that high, I max mine at 3000 at the very max.
best wireless gaming mouse, smooth, perfect feel, worth its price

Summary: If your looking for wireless with a wired option, best feel, smooth gliding, awesome build quality and performance this is it, As soon as you use this mouse in either wireless or wired you will immediately feel the advantage of using these Razer products. This wireless mouse does adds the ability to make it hard wired but why spend more if you want it hard wired when the half priced 'death adder' version to do just that (minus the on the fly dpi adjust & not wireless).
Summary: I've heard a lot of complaints about driver issues and software (Razer Synapse) issues, but I haven't had any of them. Plugged in the wireless stand, and my drivers installed no problem, switched over to plugging straight into the mouse and still no issues. Razer Synapse is simple to use and puts a vast array of different setups at your fingertips.
Summary: I was a bit hesitant to get such an expensive mouse, but I don't regret it. I've had this mouse for over a year now, and I haven't had a single problem with it. It's very comfortable and I love being able to change my sensitivity on the fly. The fact that it's capable of being wired or wireless is great. I use it wired most of the time, but it's quite handy to be able to switch to wireless when I want.
