I've seen many reviews of this puzzle and waited with high anticipation for mine to arrive. I know that many other reviewers have said the tension needs to be slightly adjusted out of the box, and that the puzzle has popping problems due to the design of the internals. I have not had any of those issues myself. For me, the puzzle felt great right out of the box and it has not popped even once. On the other hand, I am not a particularly fast solver or fast/aggressive turner. If I had faster turning or relied on more finger tricks for FTO, it's quite possible I would have encountered these problems. But if you're still kinda slow like me, this puzzle will probably serve you absolutely as well as you need. The only thing stopping me from giving it the full five stars is that a) the gray side color is kind of an ugly, brownish gray. I've gotten used to it, but I wish it was a more neutral gray or even black. b) the issues with the design of the puzzle's internals are real--even if they haven't affected me personally--so I know there's room for Diansheng to improve. I look forward to them doing so!
But all that aside: if "I'm waiting for better hardware" has been your reason for not getting into FTO up to now, you need wait no further. We have been waiting for a speedsolving FTO for *years*, and Diansheng delivered. More than that; they didn't just deliver a puzzle that is speed-solvable. They delivered a speedsolvable puzzle that is actually *good*. It may not be at the same level of awesome/fast/reliable as modern 3x3 hardware (yet!) but this is a 100% legit puzzle that brings a true speedsolving experience to FTO.
