Summary: Razer products have taken a turn for the worst in the last several years (post-2012). This mouse took less than three days for the right mouse button to fail under normal usage and Razer support has simply stated that it isn't their problem since the malfunction was likely due to "user error". The mouse, prior to falling apart, was a very well-designed and functional piece.
Summary: I checked the S/N number at the official razen website. It said the product ID is not match and I plug the S/N number into google. And I turns out that many people got the same S/N number. So it's a fake product!
Summary: i liek this mouse alot. has super high sensitivy settings and dpis and stuff. the red laser is there but it doesnt shine like regular laser mice do. this is cool cuz whenever u lift your mouse it wont shine all over the screen or bother you. seems to be rly high quality too.
Summary: I bought this mouse because I felt it was built well because it is Razer.... I guess not. I purchased it back in September 2013 and just out of the blue the wheel scroll button broke. Really?! Its like it fell out of its track. You can still click it and the holding scroll thing still works but not wheeling it... I am a little disappointed. Maybe I should have gotten a step up and it would have been OK.
Summary: Left and right buttons were uncomfortably stiff at first. They're still quite stiff and I've bashed them around a bit, but my fingers ached after moderate to low use at first. The 'feet' are almost non-existent out of the box. Replacement feet are $10, according to the Razer webpage, maybe cheaper elsewhere. For now I can't say how long the feet will last. It was significantly cheaper than a normal Abyssus mouse, however.
Summary: I bought this mouse as I needed a high (>1000) dpi mouse. The shape fits my smallish hands well. The buttons have a good crisp feel. The click is light and fairly quiet. The cord is thin and flexible as desired. The blue light does stay on unless you unplug the mouse. Also, there are only 3 dpi settings, accessed on the bottom. I use the 1800 dpi at 100 Hz comfortably. If you're picky about your dpi this mouse isn't a good choice.
Summary: PROS: - Glossy finish (might be con for some) - Compatible with OSX Mavericks (I use it with a mac) - Scroll wheel has 24 clicks - Lightweight - Overall, Good for the price As of right now, I don't have any complaints or issues with this mouse. I would recommend it to any gamer who's looking to buy their first gaming mouse.
