For those who are wondering what exactly this puzzle is, it is just a rex cube with the cuts altered to make it look better. However I don't say this in a negative way at all. Imo this looks way cooler than a rex cube, the frosted tiles which give the puzzle its colours are beautiful and offer grip for the abnormal style of turning, and the turning itself is flawless and satisfying, with a click at the end of each turn to lock the pieces into place. This reminds me of a pyraminx click but it doesn't feel magnetic or like a ball bearing, I believe QiYi have simply made the contact surfaces in such a way that they exhibit this effect at the end of a turn, which is great. In terms of difficulty ... this puzzle is fairly tough (for me) as I was attempting to figure it out without any instructions. Within 2 hours I was able to reach the last "layer" but I have not been able to make any progress beyond that since.
Overall great puzzle, would highly recommend for those wanting something unique and pretty.
