Summary: You can tell this mouse isnt quite the same standard of quality as the deathadder but its a decent basic mouse. I don't recommend for anyone with larger hands. I got this for my work mouse and am wishing now I just would have spent the extra money and gotten another deathadder. Its lower profile and less "egg" shape just doesnt fit my large hands. I am buying a different mouse as a result.
Summary: when i first got this mouse everything was fine then after about 4 months it would hurt my hand so much just to use this thing but i couldnt afford a new one at the time so i kept using it. the pain lasted about 4 months then i guess i got used to it because it stopped hurting.
Pros: 3500 dpi
Cons: bottom half of the mouse has a glossy finish and it will get really dirty really fast
Summary: I've had this mouse since October. and for the most part, it's worked quite well. It's simple, light, ambidextrous, and can be adjusted with hardware switches underneath the mouse proper. Worked out of the box, too. ...then the mouse wheel went bad, occasionally scrolling down when I meant to scroll up, and vice versa. It also took upwards of a week to secure an RMA after being asked to test it on another system.
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: Love Razer and their customer support, and the software they provide. Razer Synapse 2.0 is GENIUS. Love the idea of one program fits all. Waiting for my Razer Kraken 7.1 headset to come so I can complete my new setup of Razer DeathStalker, Razer DeathAdder, Razer Goliathus, and Razer Kraken.
Pros: Very light (almost too light-borderline con), Razer Synapse 2.0 allows on the fly adjustments to be made as well as the onboard DPI, and frequency sliders on the buttom for quick adjustments. Goes great with a Razer Goliathus mousepad. Razer customer support was great(see cons)
Cons: Left mouse button cracked while I was holding down the fire button one night. It eventually chipped off completely, and I thought razer products were made to be more durable than that, so I RMA'd it and Razer support was EXCELLENT. They kept emailing me back and forth and after I filled out all the requirements and sent images, they agreed for me to send it in so a replacement could be delivered. But, I ended up cancelling it and upgrading to the Razer DeathAdder 2013...
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.
