The DELUX M800DB is a decent mouse that is in between the popular mice in size and inspires in shape. (s) - Clicks are crisp - Secure mouse shape - No noticeable lag - Weight is similar to Razer Viper Wired Cons: - The PWM 3325 sensor in this mouse wobbles, it misses movements, but it wasn't enough to throw off my aim. But that's distracting.- The legs of the mice are very rough, they aren't beveled like their counterparts, which makes them very noisy on mousepads and you can feel scratches.- There's flex laterally, but you really have to hold that Mouse intended, lateral flex to test. In conclusion, I would say that for those who have never owned a wireless mouse, this gives a good first impression of wireless gaming mice. There is no noticeable sensor lag like there was with older wireless mice, showing how far the wireless mouse industry has come to reach this price point. The only downsides to this mouse are the legs and the tracking sensor.
