We bought two. Quality seems to be pretty high. They are actually a few inches larger than the product specs which caused a bit of a problem for us. 

But the biggest problem we have-- these things SMELL! I think it's from the packaging, but it's been a huge problem. We had to set them outside for days before we could stand to have them in the house. We've tried Fabreze, we tried to vacuum them thinking maybe we could get some of the stinky air out of the interior, nothing has helped. The smell has faded a bit, but we've had these for weeks for now and it's still the first thing you notice when you walk into our house. It's a very chemical smell, not sure if it's from the packaging or the manufacturing process, but it's BAD.
