We have a set given to the grandparents for Easter. Basically, the frame is nice (for the money) the glass does not really dibasic. The molding compound smells very strict. Rolling, even when repeated failed attempts can be easily accomplished. As others have already said, you have to press the foot or the hand very firmly in the ground. For small babies therefore unsuitable. Our impression was at the time of 5 months old. Went without problems. Wash hands after impression.
Unfortunately I can not recommend this anyway. If the ground dries, shrinks. She travels a well. After 8 weeks, everything was broken. And yes, we have the ground allow to dry for 2 days before the frame. Therefore, from me: "Stay away, too bad."
