For the price I was impressed by the quality of the parts. Everything appeared to be manufactured with tight tolerances, allowing the plastic, aluminum and steel parts to fit together well. Lots of thought went into clever design details. Stainless steel hardware seems to be high quality and hopefully will resist pool water corrosion. Assembly instructions were pretty good; a couple of places need some improvement eg a diagram shows dimensions X, Y, and z2, but the instructions don't explain the relevance of those parameters, and a table below has data that ambiguously refers to "pool width" which seems like it should correspond with dimension X, but actually means dimension Y, which is the width of the reel (a bit wider than the pool). But overall assembly was straightforward. The unit seems to operate smoothly. Hope it lasts!
