I have one, and DO NOT LIKE IT! The top PVC pipe doesn't hold down the quilt - it is constantly popping off and the tension of the quilt is gone. It becomes such a frustration!
With that said... I have used it and used those plastic "wire ties" to hold the top PVC pipe down when I am trying to hand quilt a smaller quilt than the frame. It does take up quite a bit of room, about 2'x4', so if you don't have the room consider using a hoop.
I finally have become so frustrated with this product that I have it in my yardsale pile for next spring!
