An absolute waste of money! My son is at the stage where he likes making things, he loves puzzles, lego, etc. When I came across this felt tub, I thought it was perfect for him. As he can make vehicles he loves, and he won't get bored, as he will be able to make different things every time. But we cannot even use it properly. The mat won't lie flat on any surface, I had to cellotape it to the table. The shapes are quite small and stick together, but won't stick to the mat, which is very frustrating for both me and my son. So it was money down the drain.
