By far the best mouse I've had since the Razer Ultimate. Paired with a handcrafted mouse pad, it's flawless. I used it for about 4 hours without poles and felt great until I kept slipping or double clicking. I'll update, I'll start getting double clicks, but there aren't any yet. Also, I didn't have any problems with the bottom puck getting in the way of my aim, so I used my mouse legs to hold the bottom puck and everything was so smooth with it. You really need to find an ideal spot for it to stick to, but once you do it barely bounces on the ground. I'm an avid mouse user as I practice aiming with the Kovaax every day and this mouse was so easy to get used to.
