Razer has introduced a new gaming mouse that's fully customisable and even physically transformable to adjust to any hand size or grip style. The Razer Ouroboros is somewhat reminiscent of the Mad Catz Cyborg RAT 9, featuring an adjustable palm rest capable of moving up to .9 inches (20 mm), two interchangeable side panels and an adjustable back tilt angle to ensure palm support.

Unlike the RAT 9, however, the Ouroboros is designed to be ambidextrous and can operate wired or wirelessly, running up to 12 hours of continuous gaming on a single charge according to Razer. Its single AA battery charges while operating on wired mode and there's also an included charging dock.

Razer's latest gaming mouse offers 11 programmable buttons and up to 8200 DPI via combined laser and optical sensors. Additionally, a clutch trigger lets you temporarily reduce or increase the DPI as you game, so you can "go from high-sensitivity assault to more measured sniper" as needed.

You'll be able to find Ouroboros starting in Q4 2012 with a suggested retail price of $129.99.

Razer also announced several updates to their mechanical keyboard lineup, including a BlackWidow Tournament Edition ($80) that ditches a few features for a slimmer profile, a BlackWidow Ultimate ($140) with individually backlit keys, and the base model BlackWidow 2013 ($100) with 50g actuation force, 10 key anti-ghosting, 5 dedicated macro keys, headphone/mic jacks and a USB port.
