i got one. i tried it for a short time and then stopped. the friction is REALLY high. it's too much in my opinion. it's way more than any other mousepad i've tried. you have to def liek really high friction to prefer this over the others. my wrist was hurting using it like when you use a really heavy mouse.
Do yourself a favor and look into the talent pad by puretrak. Surpasses the QcK series in all areas. I used to vouch for the Heavy over everything, but haven't looked back since I got my first Talent.
With a discount code it's under 30 eur incl shipping and everything. I can get one for you if you need it.
the ultra high friction it has after buying it new wears off after maybe 2 days of usage, after that its pretty much the same as the razer control pads.
What are the razer control pads like? Heard some people say the speed is slower like a qck and the control is faster (how that makes sense I'll never know)
