Very nice puzzle. Turning is super smooth with surprisingly little catching for a puzzle with so many pieces. Color shades are nice, plastic has a high quality feel to it. The solve is very enjoyable too. It like a combination of a Curvy Copter and a Rex Cube. However, there are a few minor issues with the puzzle. First, you can't tension the puzzle. The screws that tie into the core don't directly anchor any of the moving pieces of the puzzle, so the puzzle has a very loose and floaty feeling to it. Thankfully, the puzzle is very stable and turning is good, but being unable to adjust tensions might be a deal breaker for some. Second, the tiny inner pedal pieces tend to pop out. The pieces are made of a stalk and cap assembly, but some of those caps don't have a super tight fit. I used a bit of molding putty so I could still remove the pieces if I need to, but glue would work too. Lastly, there are some minor plastic stress marks on some of the pieces. Nothing structural, just cosmetic. Easily fixed by removing the pieces and submerging them in boiling water for a few seconds. All very minor issues, easy to fix.
