Try it first. It didn't feel bigger than the EC1 to me. Felt much thinner, but longer. It's also noticeable heavier. The metal wheel on the front doesn't help with the balance either.

it's super heavy.
the superiority of the sensor is nothing compared to this flaw.

It doesn't even have rgb lighting with 16.8 million colors.

Thinner doesn't make any difference to me. And the weight issue, I actually like because the Zowie does feel cheap because of the weight. I always feel I might break it.

But I actually want to know what has the better sensor?

I'm really loving my Xornet CM storm. I had it given to me for free after my g400s went tits up (long time 510/518 usr) and I wont be going back.

Low centre of gravity.
Light.
Up to 1000hz by default.
Nice rubber for left thumb
(no drivers I think)
using it on an OLD OCK+cloth.


I'm out of the loop with high end mice, but I consider this a lucky find.
And trust me, I'm hardly mister complacent when it comes to mice.

If what went wrong is the cable, then a cable fix isn't too fix, there is at least one written tutorial I can remember on how to fix that.

playing with this mouse for six months.
ive adapted from small g100s fast and easily. weight doesn't bother me at all from start.
additional buttons, led can be disabled.
