At first, I was really skeptical when I ordered it. I mean, it is an empty cardboard box that you should be able to sit on without getting injured, and it should produce nice sounds too...it doesn't sound so promising, right? Well, it's all true.
It really sounds like a musical instrument, and most importantly, it is very durable. I weight 96kg and it can hold me without any problems at all. I have a friend who is a bit bigger than me(120+ kg) and he was playing it for about two months almost every day...it is still as good as new.
For this price, you can just get it for playing around, or you could even use it as a reallly weird looking chair hahah. Definitely a good buy... :D
