Summary: It would be fine if Cooler Master honored their 2 year warranty but they don't have any form of Support. Just automated emails and people who send old/outdated pdfs to tell you to do this or that to waste your time.
Pros: It's a great mouse when it works, the multi-buttons for sensitivity are great to quickly adjust between mouse speeds
Cons: The product is flawed and bad. Mine started breaking at around 6 months when the sensitivity died and only had one sensor speed. For this it then lasted until 9 months and stopped working altogether and won't work on any computer.
Pros: It is an ambidextrous gaming mouse! Being left handed, and having a son who is right handed and shares my computer, I usually ended up having to deal with his right handed gaming mouse. This usually meant I would have to disable all the buttons except 1,2 and middle, lest I accidently hit them and randomly chuck grenades (or whatever they were set for). I ended up buying a cheapo mouse and kept swapping them back and forth depending on who was using the computer. Now ...
Summary: A very good and high performance gaming mouse. Only about $14 after tax and mail-in rebate. LEDs are nice looking. Only complain is that there are 4 side buttons on both sides, and sometimes it is a little too easy to press them by accident. It's annoying when you're browsing and hit the back/forward buttons, however those buttons can be disabled by software so it's not a big deal.
Summary: This is a $40 mouse all day. That competes with the more expensive mice out there. I know i have most of them :) If you can get it on sale Bonus! this mouse coast $15 after tax and rebait.
Pros: Software is awsome: gives you full control over the mouse., 3 color change with the push of a button., good for people with smaller hands. :), buttons are well placed. As good as you can for a mouse.
Summary: My logitech g500 started registering single left button clicks as double clicks, so it was time for me to buy a new mouse and I bought this one because it had a nice discount on it. Anyways getting down to the mouse itself, it's absolutely amazing. They got almost everything dead on perfect, in my opinion. The sensor is flawless (no acceleration, high malfunction speed etc.
Pros: - Flawless sensor, - Rubber coating, - Omron switches give a nice click feel, - Suitable for both palm and claw grip, - Ambidextrous design
Cons: - May be too small for larger hands, - Forward thumb button is questionable
Cons: The space beneath the side buttons, where one's thumb rests, on the side of the mouse; is not quite as sturdy as I'd like - As there is already some definite signs of wear. Nothing terribly major to note, though.
