Yes, the seller had it popped up when I got there, and he lowered it for me, no problems noticed. I really should have looked over EVERYTHING more closely. I rushed through it. On Saturday I contacted the seller and shared the struggles I've been having. He did say that twice one of the posts stopped about halfway up. He would shake the post a little and then it would work fine.Did you see the top go up and down when you looked at it before purchase?
