Decent puzzle, poor stickers. Very floaty and prone to misalignments. The curvy copter plus is a better puzzle in pretty much every way.

This puzzle does almost everything right. Turning is great with minimal lock ups. Plastic quality is good. The solve is fun too. It's in that sweet spot of not too easy, but not too challenging. My only complaint is that the stickers were already peeling a bit when the puzzle arrived. I'm sure it's not a big deal for most people, but it's annoying for people who are OCD about stickers like I am. Great puzzle otherwise.

I didn't expect the curvy copter to be very challenging, but it was. After developing a few algorithms for it, I managed to solve it with some complicated conjugates. After I solved it by myself, I went online and found simpler methods and algorithms. It turns very smooth and never popped. It jumbles which adds an extra challenge.

This puzzle looks nice and turns really well. It's fun and challenging to try to figure out how to solve it, and the fun doesn't wear off as nearly the whole solve is intuitive ( needs no algs except for last two steps) making the puzzle a challenge every time.

Not many edge turners exist. There was the original helicopter cube which now only lives on in knock offs, I was lucky enough to get an original when it came out, but didnt overlook this puzzle, although it adds so little to the solve that it is negligible, the appearance is beautiful and the movement must be felt to be believed. Furthermore, the original helicopter cube was a bit bigger than standard which was fine, but the nice compact size of this helps differentiate them more.

The Meffert's Curvy Copter is a great non WCA puzzle for collectors. The cube came with decent stickers and I have not replaced them. The turning is decently nice and it flows somewhat well. The jumbling adds a great challenge to the puzzle and overall very fun. I would recommend getting this!
