Very flimsy and not easy to assemble. I can't imagine doing this with one person. The places on the poles to do the height adjustments are way too low. It has you doing contortions to hold the top of the pole in place while you adjust the height and tighten it in place. It is in place and doing the job but I expected better from Umbra. I generally love your products and have purchased several but this was a disappointment.
