Razer Mamba

Pros: Quite physically robust
Feels nice to hold
Works on pretty much any surface
Reasonable battery life

Cons: The sensor algorithm - If you lift the mouse up and down vertically, the cursor moves towards the bottom right of the screen. If you tap on the top of the mouse, this issue causes the cursor to slowly drift in that direction.

The little rubber pads on ea

Summary: It's okay, but the number of flaws is inexcusable especially for this price.

I preferred my old Logitech G7 which, while was not quite as physically robust, didn't suffer from any of these issue and much more thought seems to have gone into it.

From my experience with their products and their technical support, Razer seems to be a company where they think of a few key features that people may want, then rush out a product and don't care about solving any of the issues the users have reported.

It seems the cons didn't send properly:

The sensor algorithm - If you lift the mouse up and down vertically, the cursor moves towards the bottom right of the screen. If you tap on the top of the mouse, this issue causes the cursor to slowly drift in that direction.

The little rubber pads on each side - As your fingers press against these, the ends of the pads lift away from the double-sided tape holding them on and they slide out from the little cutouts. It's quite annoying to have to keep sliding them back into place.

The battery - The lack of easily inter-changeable "Hot swappable" batteries means that if you forget to leave it on charge overnight, you will need to plug the mouse in in-order to use it. It's quite annoying to not be able to use it wirelessly indefinitely.

The drivers / firmware - My mouse has an issue where sometimes when it's turned on, the buttons will work but mouse movement does not. I also find the configuration software to be a bit too messy and flashy.
