Question: I ordered 3 of these. They are sturdy, comfortable, and stay inflated. The electric motor in each easily and quickly inflates and (almost) deflates them. The height also makes them feel more like a real bed.However, if you want to completely deflate them for storage, that can be a real trick. I could never deflate any of them completely, so in frustration I cut one open to see what the problem is. A design flaw allows an internal plastic flap to cover the deflation port when they are almost empty. The more you try to vacuum or squeeze out air, the tighter the flap seals the port, sealing in the last bit of air.Now I know, and there's nothing I can do about it, but I feel better after attacking one with scissors...

Answer: Negative


Question: This isn't the original art for these books. They hired a cheap hack to make the illustrations "less scary". The original had a better artist and better illustration. Dont waste your time on this pussified version.

Answer: Negative


Question: The scene itself is beautiful, but finding the correct fit for pieces is difficult. Most pieces are of similar shape and often multiple pieces with similar colors actually fit into the same place. The lack of piece shape diversity makes this puzzle annoying to me, perhaps challenging to others. This frustration did not make this a "fun" puzzling experience for me.

Answer:
Negative
