I bought the 52 in. Like everyone is saying, directions aren't very clear but I found an assembly video to follow, still wasn't the best but I managed. Got it built fairly quickly and came with extra pieces of all the hardware. Had the gloves, screwdriver and a lil sanding pad, but didn't have the feather toy, which is ok cause I don't need it (just a warning incase you do want it). Sadly the carpet doesn't fit as well as expected, even after adjusting it a few times the ends still over lap a little bit. It rotates easily and is fairly quite but can still be heard when the house is quiet and I'm in the other room down the hall. Male will play on it for the most part with a laser, but female isn't too fond of it, but it's only day one, hopefully they warm up to it and will use it on their own.
