Then the bottom screw was crooked, which caused the screw to snap and I could not tighten it.

The screw that holds up the stand came broken, making the stand completely useless.

These screws are cheap, and hollow on the inside.

The middle adjustable screw, out of the blue, doesn't loosen well

Flimsy, bottom screw wouldn't tight, once the whole thing came out next to my kids

Also the top thumb screw that holds the top stand in place is not strong enough to hold a book in place.

The stand received is not the stand shown in the photo - friction screw adjustments rather than lever adjustment.

The screw broke right after the 30 refund policy.
