DaYan FTO (Magnetic + Ball-Core)

Perfect

Easily the best FTO currently on the market it has amazing turning and I have not experienced any pops so far. It is a great upgrade from the diansheng and the larger size is a lot more comfortable to hold, the turning is great and extremely smooth. AMAZING puzzle!!!
