Great product, great idea. Unfortunately it comes in standard factory packaging WHICH IS COMPLETELY NOT SUITABLE FOR USPS MONKEYS. So mine came with all 4 corners bent, paint cracked etc. on .Half an hour in the garage with pliers, wood, clamps and cardboard.Finally I have it back in usable condition.The seller must ask Revain to ship it in an outer box to protect the tray.Otherwise the tray will warp USPS and break in the corners. Like mine. :-(
