Top optical sensor, optical switches, soft braid flexible cable, light weight small mouse all for a relatively low price ($39.99, could've easily charged more than that). This is basically a smaller Razer Viper with the back left high, kind of like a narrow Cooler Master MM710 shape wise. The back hump was a bit wide on the MM710 so this might suit those people. Pretty amazing mouse, definitely worth a look if you're in the market for something small. The Finalmouse Ultralight 2 is still smaller and I found myself aiming better with it still, 10g different and shape, but this is a close second and a third of the price. I'm not sure of the latency on this mouse, it's either 0ms like the other Vipers or 4ms. Razer say the same as the others but the bump test just isn't working with it. I'm going to trust Razer for now and say 0ms (so a bit faster than the G903).
