If you are looking for the worst… buy this
I ordered two of these for a school classroom. Not only did they not provide enough connecting screws for the wheels - in either package - they ones they did provide were too long and could not be fully screwed in. I could see if it was one of them, but both packages had the exact same error. Please don’t buy this. You will only be frustrated.
