Good height range
Plastic is a little flimsy. One of my connectors broke when I was putting it together, although to be fair I was probably pressing too hard. The break was minor and did not affect function.
Vertical poles spread towards the top so the bar doesn't have much to rest on at the higher levels?
One more note, my item arrived missing one of its jump cups. I DID NOT attempt to contact customer service, so to give them the benefit of the doubt I will presume that if I had, a human being who spoke perfect English would have answered on the first ring, apologized profusely for the error, and had a courier hand-deliver a replacement the same day. If only I had given them the chance to show off their remarkable customer service! Instead of replacing the jump cup, I purchased a pair of jump cup strips that screw into the plastic uprights and let you change the height just by moving the bar. I have been very happy with this arrangement so far, and am satisfied with my purchase.
