Quality
Color: Missouri Tigers, Size: Large
So i got this for my dog who was board and distroying the house and or having anxiety attacks. This was a cheap option and he loved it as a beginner puzzle. The covers slide so easily and don't stick like wooden puzzles. The amount of treat pockets is also great. The dog doesn't care what team it is related to and neither do I. If you are looking to keep your too smart dog entertained, tis is for you.

May Pose Choking Risk
Color: Mississippi State Bulldogs, Size: Standard
As far as the puzzle aspect my dog was not interested but it did entertain him as a chew toy and the base held up pretty good. Take note though, the brown blocks come right off and may pose a choking risk.
