I recieved the Razer Mamba ,,,, here is my review.
It comes in a thick glass and has very sexy looks and comes certificate and bunch of mini books. Im using the mouse with the cord because the battery needs to be chaged but I need to use mouse now,, and I dont wanna connect my ole Lachesis dont have time for something to go wrong. Also this came with latest firmware so no reason to update firmware.
The Dock is soo stylie,, its sexy ,, the battery and underneath of mouse is top notch and I do have the black ring around the sensor area for friction so it doesnt move for no reason. Soo far with the cord I feel a difference from m y Lachesis,, Lachesis was nice 4000dpi but it had issues with friction, and how on a cotton pad which I use it would move the cursor would move on its own. Anyhow. I cant wait to use it wireless and see how that goes. I dont know how long it takes to change it. This was totally worth it,, its nice for my DAW as well,,, soo smooth and solid. Its worth it. Soo every night Im gonna put the mouse on the dock soo I have 16 hours worth of time which is enough.. I charge again each night.. amazing,,, soo stylie how it comes and how ieverything looks and what not.. It doesnt glow the Razer logo on the mouse like the Lachesis and Copperhead which is a downer, and also lacks the pinkie buttons like the Lachesis and Copperhead and diamond back. The two small button on the front I leave to adjust DPI ... I use side button as secondary attack and other side button as whatever I would put m pinkie usually too.

Soo far IM a happy customer Ive payed 100 dollars before on mouse in 1999 boomslang I payed 110 free shipping from
www.amazon.com and its worth it,,, cant wait to get it charged soo I can use without cord. everything on this is high tech,, wheel is nice,, there notches as usually unlike cheap mouse which it just roles,, doesnt click,,, feel is great, I would say its feel competitors is a G7 carbon fiber new version. Its perfect fit for me. I got large hands not medium.... its great I will get use to it in no time.... Also the mouse came with a black ring around the sensor,, which gives it friction soo I can use it on cotton pad unlike Lachesis the cursor doesnt move on its own... good stuff... Takes 3 hours to charge either on dock or connected wire mode. Last 14 hours of hard core gaming, and 52 hours of regular gaming or non gaming.
