If you've ever toyed with prior Razer mice and came away impressed, you'll be even more so with the Mamba -- good luck keeping that credit card close to your posterior.

The Razer Mamba provides unmatched precision whether it's connected directly to your PC or set free in wireless mode. If Razer fixed a few design and features issues, we'd feel better about the price.

If you really want or really need the wireless, though, I’d say this is the best wireless mouse you can get, with the possible exception of the Logitech MX Revolution, but that’s a tough call.

Gaming-grade wireless is here (just in case you doubted it), and performance isn't the reason you should pick the Mamba over the X8. Mamba has better design, feels better (especially if you have smaller hands) and more functional software.

The combination of true wired performance, wireless convenience, superb styling, and amazing ergonomics make the Razer Mamba quite simply the best mouse we've ever tested and it will take something seriously special to beat it.

If you can spare the cash and you are as impressed by the Mamba's features and style as we were, this might be the mouse for you.

The cold war between Microsoft, Logitech, and Razer just heated up some more, the bar is raised a little higher—thanks in large part to Razer’s newest weapon: the Mamba.

We’d much rather have an awesome wired mouse than have the battery conk out during a heated TF2 match, when there’s nary a moment to connect the cord. As it is, the Mamba is a great wired mouse at a price that’s high, even for a wireless mouse.

If you're after a top-of-the-range mouse, go for one of those and do something worthwhile with the extra £70 you'd spend on the Mamba. It'll garner much better Karma…

The new Mamba offers a good shape and excellent performance with the highlight being Razer's new 4G sensor which gives us a phenomenal level of precision and a great lift-off experience.

It is a comfortable, well made, premium product with more features than you can shake a 1m-long braided USB cable with gold connectors at. That said, it's very hard to imagine who could justify buying it, especially when there are some great mice ... available for a lot less cash.

If you want the very best mouse money can buy then the Razer Mamba is undoubtedly the best mouse for you. If you want the best bang for buck then you need to look elsewhere.
