had the pleasure of getting a diansheng FTO from diansheng directly as a chosen tester, and it is such a marvelous little cube. it's noticeably smaller than any other FTO on the market, but its is really pleasant to hold in the hands, and its pretty fast. there is a small range of tensions that work on it, slightly tight. any looser leads to edge explosions, which are unfortunately not that uncommon. it is such a smooth cube, something lube only helps. i can easily do hundreds of solves on this and not get tired. already got down to a global of sub 26 after just less than 2 weeks of getting it, and have done about 2100 solves on it so far. highly recommend everyone to buy this if you are looking for an FTO
