Small stain in top, shown in closeup picture.
This wobbles a bit, and always has done.
I am sure that a diagonal cross-brace to the legs would stop this, but it would preclude folding it back to half size, so I've never bothered.
If you are interested in it but worried about getting it home, I can dismantle to step 1 by removing the top or to step 2 by also dismantling the frame to separate legs cross bars.
You will need an Allen key to put it back together.
