I got this for my birthday 10 months ago, and it has performed incredibly well, getting me all my PBs on 3x3 and OH. But yesterday I decided to change the settings to something more like Yiheng's. I put it on tension 2 and compression 2. The next day, It popped, and a centre snapped off. Would recommend other cubes over this if you are a rough turner or like loose cubes. Yiheng has his WRM v11 super loose, and it doesn't seem to cause him any problems. I've also never heard anything about this from the RS3M v5. All in all, this cube is pretty much outdated. Buy the v11 for a few quid extra, and get all the premium features. Or, if you want budget, all of the features that this cube has (minus the fancy adjustment system) can be bought for £19 with the RS3M v5.
