I'm giving this five stars in the view of a teraminx, not an ordinary puzzle.
Turning: Outer turns are great and very smooth. It turns better than a well-work Rubik's cube. A little less smooth than a well-worn V-Cube 3. Two- and three-layer wide turns are also pretty good. You're moving a lot more pieces, so there is some more inertia, but it feels good. Locking is common. I don't think that can be avoided for these larger puzzles. Can it do slices? No way!
Feels: Great. No stickers are the major selling point here. The pieces feel good have a nice a grip to them. The perfect blend of rough and smooth.
Would I recommend this puzzle? If you want a teraminx, then this is the one to get.
