My daughter hated it from the first day. She would start crying the second I put her on the board even if she would accept a bit of a tummy time as a very young infant. I kept on trying it regularly, even when she loved playing on her tummy, I got the same answer, cried to put her down. The mat is very colorful, but has little toys to play with, so she would scratch it for a minute or two then look for something else. With the baby's weight on it is too difficult to spin for an infant, so I would have to spin her slowly, still she hated it.
Do not buy it! It's a total waste of money and space to put it away!
