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: The mouse itself works fine. It has good DPI, and switching between frequency and DPI just by turning it upside down and flipping a switch is convenient. The drivers for the software are buggy. I need to unplug and replug the mouse every time I shut down, causes blue screens if I'm not careful, and will not set scroll speed lower than 10. You need to go into system settings every time to set scroll wheel speed to a more sensible number.
Summary: If you want a small mouse with really high DPI and no extra buttons to get in the way, then the Abyssus is a decent choice. Just don't get the Mirror edition. The matte version of this mouse will stay much cleaner.
Pros: * Durability. I've had it for over a year and I see no signs of it degrading in quality.
Cons: * Attracts grime. I have to clean this thing constantly, else it becomes covered in grime and oil. It's funny that the "Mirror" aspect of the mouse (the glossy finish/material) is supposed to be a selling point. When in fact, it is probably its biggest con for most people.
Summary: The mouse itself isn't bad. I'm left-handed and the ambidextrous design works well for me. The mouse is a little light, but it feels okay in the hand and slides very smoothly. Just don't expect a tank. The drivers, on the other hand, are horrible. Every application had different scroll wheel speeds and I had to constantly rest the scroll speeds. I finally uninstalled the drivers and am using the default Win7 driver.
Summary: I used this mouse for only about 2 weeks before having to return it (see cons) Pros: *Lightweight body and cord give speedy navigation *Mechanical DPI and polling rate switches work as advertised. Software sensitivity adjustments in game options were necessary, though painless. *Aesthetics are nice, with the razer logo and soft finish. Mouse's bright blue light is on if the computer is running, which doesn't bother me but might concern others.
Summary: A great mouse if you only need two buttons and a scroll wheel. The first time I purchased this mouse the left mouse button failed after only a year of use but the design and feel of this mouse in my hand along with the DPI and Hz settings made it worth buying again. I would recommend shopping around and being certain this is the right mouse for you before purchasing.
Summary: I bought this for my girlfriend and although it worked well for her, who prefers small mice, it would sometimes act up. It would lag a bit or jump to random directions. However, after she started using a decent mousepad, the problem went away and the mouse works like a charm!
