Great product, it gives the animals so much room to run around. It seems to be very sturdy and will hold up for quite a while! 
I am not so thrilled about Wayfair. I waited three weeks for the item to be delivered, even though it said it will come in 7 - 10 days. After it didn't arrive on the day promised (I tracked via UPS) I called and was told that UPS lost it (really???). They promised me to get it within 3 - 5 business days. It came finally a week later and I had the same tracking number. How can this be when it was already shipped before? So my guess, they forgot to send it. The customer service agents were very nice, though.
