The quality of this isn’t amazing which was shown by my first delivery which had a bent frame (to be fair this was most likely to couriers fault) and my replacement item had a faulty popper. So definitely room for improvement however the rest of the carrier seemed good value for money. The wheels were basic but could be pushed easily on bumpy surfaces and my dog was happy enough in it. 
Wayfair customer service was amazing when dealing with my issues quickly and easily, which is a rare thing from most companies these days. So although I’ve had problems I will shop with them again in the future.
