Overall it’s a good fisher cube, but it does catch and it does require tensioning. The main problem I had with this was one of the orange capped pieces was actually molded too big for the puzzle so when I made a turn it would pop off every time. I actually had to take my mitered cutting shears to trim off the piece so it would fit properly. After trimming the piece and glueing it down it works fine. Smooth and quiet. Shades are nice and vibrant. Plastic doesn’t feel like great quality but this is only a $4 puzzle. Can’t expect more.
