Query: Don't buy this

This product was great after we managed to get it put together and it stayed together for the first two months but after that when we have used it, the sides don't stay up, it is difficult to fold up and within the first 6 months it has cracked and the side release buttons have broken. Combi customer service has been difficult and said they would replace it and then have denied saying they would replace it. I will not purchase Combi products again.
