We recd, the large dog crate, it came in nice, except when we opened the box from the manufacturer, and started to assesemble the crate, when we got to the side panels of the sliding doors we noticed that the black cage slots were not soldered down or they just broke off from there soldered welt, there were 6 pcs, of the cage not soldered down or broken off, 
I wish there was a way you guys could of checked the quality of the cage before you shipped it
So, needless to say, we are not using the side, we have it so taped up, and will only use the front entrance, please check other peoples cages before shipping,
Thank you
