FK2 vs FK1 vs G403 vs EC2-a quick reviews

Zowie FK2
The first one I got. The difference from my cheap microsoft mouse was incredible. My aim was a lot better and I had so much more control. The shape is great but it was a bit to thin for my hands.

Pros

• Great cable. (goes for all Zowie mice)
• Build quality felt good, nice stiff clicks and no rattle.
• Good side buttons

Cons

• Just that the mouse was a bit to thin for me personally.
• Scroll wheel is not great.

Logitech G403

Pros

• Great sidebuttons, the best of all the mice I tested.
• Great build quality
• Good software, that lets you decide coloe / turn of the LEDs

Neither pro/cons

• Great sensor, felt a bit "sharper" than the 3310 (in all the Zowie mice) but I actually prefer the 3310, even though 3366 is objectively considered better
• Clicks felt good, but really light. I prefer more stiff clicks.

Cons.

• The cable is horrible, the worst cable I've ever tried actually. Stiff, heavy and braided.
• The bump felt odd to me (which others have also said) But maybe I would have got used to it.
• The mousefeet wasn't as good as the Zowies

Zowie FK1

Pros

• Same as FK2

Cons

• My FK1 had a pretty bad scroll wheel rattle.
• The FK1 was a bit to big for me and felt a bit clumsy, and I couldn't comfortably reach M5.

Zowie EC2-A

Pros

• Cable is great as with all Zowie
• Great shape, really comfortable while still being small and easy to control.
• Better scroll wheel than the FKs

Cons

• You can't turn of the scroll wheel led, or choose color. Really annoying in a mouse for that price.
• I can feel the clicks in m1 in my m2 finger which is a tiny bit annoying and that wouldn't happen if the buttons were separated from the shell, which I think is what most people here prefer.
• The side buttons are a bit mushy and have a lot of travel distance. But i really like that they require very little force to push.(compared to the FKs)
