The Behemoth is like the Eclipse a fine mouse considering its price. However it does have some flaws that make it less attractive than the Eclipse. If your hand fits the Behemoth, it can be just as good as the Eclipse, but if it does not, you are going to get annoyed pretty fast.
The sensor performs nicely and the low lift off distance is really neat and makes the mouse more comfortable to game with. This is because you do not have to lift it a lot to get the sensor to stop tracking. The glide and general precision of the Behemoth's 3G laser sensor is really good, the perfect choice for high sensitivity gamers.
