Looks good to me, I like the design, but you never can tell if it's gonna be good until you get your hands on it & use it.

I think once you find a mouse brand you really like it's near impossible to be happy with a new mouse. It's down mainly to the muscle memory of your mouse hand. I've used the same shape mouse now for nearly 8 years. Logi MX518 lasted me for about 6 years believe it or not, it still works fine now but i upgraded to the G400 one. If you do use your mouse a lot as i do then using a new shaped mouse will take at least 3-6 months for you to get used to it. I was looking at some of the new Gigabyte mice and i think they have flat out copied the mx518 shape. This X2 Genza Gaming Mouse does look really nice though.

Logi MX518

mx300 for me. i changed over to a steelseries sensei a few years ago which is just about the same and makes sense in my hand. however ive been wondering about the func ms3 and its pinky holder. cheap enough to try, i think. anyway, classic logitech ftw!

Still using my 5 Year old G500. Earlier this week i got the G602, but i was a bit disappointed with it. I RMAed it for a replaced which is going to be the G402. The G402 is closer to what i'm used with.

Are the sides open and not encased??

"perfect ergonomic comfort" yeah right, symmetrical mouse being perfect...

G9x for me - recently went from cloth pad to steelseries 4HD mouse pad, so much better with that mouse pad!

I dont like it ,,not enough buttons and not keen on the open sides , i will stick with my G700S Rechargeable gaming mouse, best mouse i've ever had so far and i've been through a lot of them in past years .
