this cube is definitely worth it! With enough work (breaking in, lubing, and tensioning) it will probably replace my Moyu pyraminx.
For those who are willing to read a longer review, this pyraminx is great. I first tried it out at Princeton Winter 2016 and instantly fell in love with it. The guy said that he had broken it in, tensioned it, and lubed it (not sure what kind of lube). I was able to beat my PB twice! Honestly, I would recommend this to anybody, whether they be a beginner or advanced solver!
