Presentation is key. You can tell a company thinks its mouse is good when it arrives in a perspex enclosure, mounted like an expensive artefact in a museum.
This is the second Mamba to bear the name, and arrives equally as audaciously as the first. It's Razer's wireless gaming mouse, which comes with a docking/charging station that glorifies it almost as much as its packaging and has a glowing blue light around the rim, and acts as the wireless receiver. If you prefer corded mice, you can also use the USB cable from the docking station to plug directly into your mouse, bypassing the whole wireless thing altogether. This is, incidentally, another way you can charge the battery.
Razer's made some tweaks, of course: the most notable being the larger capacity battery, now clocking in at 1100mAh instead of 800mAh so things last a little longer on the battlefield. The USB connection into the mouse has been modified so it slots in easily, rather than being an ordeal. Ah yes, and there's a brand new sensor in here, too, which uses both an optical and laser sensor for increased accuracy, and everything that lights up now has RGB LEDs in it so you can choose whatever colour you like. It even does spectrum cycling, with the mouse changing colours perfectly in sync with the docking station. Overkill, Razer's heard of it.
For the average gamer, though, the most welcome point will be the new price. The original Mamba, whether because of exchange rate or otherwise, had an RRP of AU$299 in Australia at launch. The new Mamba? AU$179.95. This is still significantly more expensive than the US price of US$129.99, and even local retailers hover around the AU$160 mark, so if you can minimise your shipping costs from somewhere like Amazon US, it might be a good idea to import.
