Pretty easy to set up (if you follow the instructions), holds together pretty well.  The "folding" feature is difficult - it would be nice if the PVC pipe and fittings fit together a little better, since the pipe usually either barely fits into the corners, or it's difficult to get the pipe out.  But if you thump the pieces together with a rubber mallet and don't try to get them apart again, it's a terrific piece of equipment.
