I just got this cube a few days ago so I decided to use it for a while and then write a review. OOTB, the tension was very loose, I've got a few pops during solves, it can cornet cut a little more than 45 degrees for both normal and reverse cut. It's very fast, so I took it apart, wipe off all the factory lube, and then lube it again with Silk, now it's more controllable. The only problem is the stickers, they feel very cheap, it's like the stickers were made by paper, and I can see some white dust on it, but no big deal! I would definitely recommend this cube to anyone who averages around 18 - 30 secs on 3x3 !
