I love the size and shape. Fits well in the stop I had pick out for it on my porch. Does take a few days during cold weather to warm up, but I knew this ahead of time, and totally understand the type of heat used to warm up the water. I do not have a problem with this, once warmed up the pump will turn off automatically and back on when needed. If you leave the top on it will keep the warm nice and warm for a longer period of time.
