When I first got this, out of the box it was really stiff and had a dry feeling to it. You could definitely feel the plastic grating against plastic. But with correct tensioning and lubrication IT WAS AMAZING. This cube has so much potential, but has a tendency to overshoot when turning it. I recommend that you are at LEAST sub 30 seconds, otherwise you may not be able to control the speed of this cube. It only has its maximum potential if you can control it properly. Unlike a Zhanchi it has a very fast springy feel, there is not much of the clicky feeling you get in the Zhanchi, it feels more like a Wittwo 2*2, if you own one you know what I am talking about. It feels almost scratchy. Overall turning quality awesome, cornercuts 45 degrees easily, reverse corner cuts a whole cubie, and the stickers that come in with it are your standard Dayan stickers but unlike the Zhanchi the stickers are smaller, I recommend you replace them. I highly recommend this product to anyone who is interested in a VERY fast cube as a main to use at competition or just for fun.
