his is a fun product! If you want your kids more intelligent, indefinitely recommend you get this to them. Once I got it, I don’t even know how to play it, but my kid starts to play it .it can make her stay at a spot around three hours, and she never get bored about it. It’s a great product!
only downside Just nuts and bolts. It’s a good product but would be better if it had some wooden nails also.
