The first one I got was good except it sags over time no matter how tight I tighten it. I've tried all suggestions to no avail. So I sent it back and after a bit of work, use and what I would call a short break, I was able to hold my very old, very heavy iPad with no problems. Very good and quick replacement. No problems or questions.
