My 2 year old daughter has only used it a couple of times and one of the sharp metal wires broke the nylon. I didn't notice and my daughter walked through and the sharp metal wire sticking out clawed her side leaving a big scratch that bled. I'm so disappointed because the few times she's used it she really loved it. The metal frame is so sharp. Of course, this happened right after the return or exchange option expired. I hope the seller sees this and offers an exchange or refund.
