great feeling puzzle for beginners to the heli series of puzzles, this one and the standard heli are combined in the curvy copter puzzle so buy this and that before you attempt to solve the curvy copter, I feel this puzzle is great for modding and if you really want to the core is the same as the one that can do the 2x2 turns as well so all you need to do is cut the pieces down the middle to make it do the 2x2 turns as well

Well built quality. Nice and smooth turning. It comes with a very nice clear plastic display box. Quite fun to solve this puzzle cube. Like it!. J2018
