Very happy with this purchase.  Arrived on time, packaged well, no bumps or bruises.  Definitely a 2 person setup.  Only two minor issues with factory ‘machining’...we had to remove & reposition the front door magnet to allow the 2nd door to close & one of the screws holding a corner of a screen panel in place at the top was stripped out - everything is secure without it.  We discarded the plastic cam covers as they easily fell off and I didn’t want my dogs to swallow them...they are for aesthetic purposes & on the inside anyway.  It’s sturdy and overall a good design, but I agree that the tray liner would be better if it was slightly larger and fit snugly.  Perfect size for my 2 doxies to share.
