Today my Razor Mamba (original) died. It had been acting funny for a few months, going slower all of a sudden and then recovering. Now windows says its failed and I get nothing out of it. Every moment I had that Mamba I loathed it.
I came from a Logitech G7 and before that an MX500. Its not that the Mamba is a bad mouse or that its uncomfortable, quite the contrary I loved the feel of it in my hand. No the problem I had with it was the drivers (wireless was unusable especially) and the general feel of the movement. The movement feeling is odd, it could just be its different to the logitech algorithms but whatever it was that was wrong I never in a year and a half felt fully comfortable with it. It has impacted my FPS gaming quite considerably and yet I persevered with it because its an expensive gamers mouse! But what I did like was the low height of the mouse and the general shape.
Moral of the story is - go play with the damn mouse in a store especially if its £100!
