Bought two of these. The first, the ball bearing that rotates the stand, was a bit loose but still workable. I got another one for my second iPad 12.9 tablet and thought the second one would be better but still the same problem. They can be used but I'm disappointed that I can't adjust the stands to the correct angle. The height adjustment is a big plus, but the ball bearing inside is underpriced and loosens with use. The weight of the iPad 12.9 isn't the issue as I've tried smaller tablets with the same issues. Added September 14: The seller has contacted me to resolve issues with the stand. So this is a huge plus for standing behind their products.
