Pros: Comfortable, Excellent Tracking, Adjustable DPI, No fancy marketing gimmecks
Cons: it's not cheaper?
Razer Tempest > Microsoft Intelli 1.1 > Logitech MX518 > Razer DeathAdder > Logitech G500 > this mouse
First off, I ordered the blue edition for the full rubber coating, and no glossy sides. For me, glossy mice get slippery after awhile of gaming, and they collect fingerprints which drives me mad.
The size of the mouse is just about right, not to big, but not to small by any means. The mouse is extremely comfortable, and with the rubber coating is easy to grip no matter your grip style. (Although I would say this is more of a palm grip then claw grip mouse)
The DPI has three settings, and that's it. No fancy drivers that are system hogs, no extra software needed at all. Which I consider a plus. The cord on the mouse is probably the most flexible cord I've ever owned. It's thick, but doesn't bother you one bit while gaming.
As far as tracking, I feel it is spot on. The only mouse that I've owned that I can compare it to is the deathadder, but this has MUCH better build quality in my opinion. I always thought the deathadder just felt like a cheap plastic mouse.
The buttons on the mice have a nice click feeling to them. The scroll wheel is just a bit stiff, but it will loosen slightly over time, and should be perfect once broke in.
I enjoy heavier mice (had all the heavy weights in my G500 if that tells you anything) and the EC2 is perfect in that department. Glides easy, but not too easy. (using on a QCK)
Speaking of gliding, the factory feet on the mouse are amazing. I've not seen anything like them on any of the previous mice I've owned. A big plus for me there also.
Overall, If you are in the mood for an accurate tracking mouse, but are tired of the sub par build quality of other mice, and the horrible drivers that go along with them, then definitely check into the EC2. I am extremely happy with my purchase, and I would imagine you would be to.
EDIT: For some reason the system classified this under "Zower Gear" and not "Zowie Gear" and also I own the EC2, again the system labeled it the EC1, which is incorrect for my review
