I've been sceptical of wireless mice for a while, but when SteelSeries released the Sensei Wireless I had to give it a go. I own a regular Sensei mouse and in my opinion it's fantastic, with a ridiculous amount of customising options and features. The Wireless Sensei carries over all of these features, which is great. I haven't experienced any latency issues at all so far, and charging it is easy enough via a USB port on my computer. Would recommend this mouse to anyone wanting a wireless solution for gaming, but don't want to sacrifice a bunch of features.
