We love the double crate. It holds both of our dogs which are between 50-65lbs and looks fantastic. It did take a few hours to build but I found the instructions to be very straightforward and easy to follow. All you need is a Phillips head screwdriver and you’re good to go (an electric screwdriver would be even better). The only gripe would have to do with the gate locks. When built, everything was lined up and great. Once we moved the furniture, the flexing of the piece from lifting both sides threw the locks out of alignment so we had to do some manipulating to reinstall the gates to line the locks back up. FYI, I used toothpicks to insert in the screw holes and snapped them off in order to created new holes for the hinges. Now that all is done, all is well and our dogs hopped right in. Would highly recommend this piece.
