The unit is of a very high quality. Surprisingly sturdy and well constructed. I expect it to last for many seasons and it quickly became our pool's favorite feature. We had the sleeve grounded and embedded when our concrete patio was poured, and from there, slipping the pole into the sleeve for final installation was a breeze. The unit arrived quickly, and was several hundred dollars cheaper than buying it from my pool installer. I love the fact that it's acrylic and doesn't detract from the view. The only drawback is that with our salt water pool, you can see water marks on the acrylic once it dries. A quick wipe with an old towel while damp solves that problem though.
