Early in the pandemic, (April 2020?) we decided that if we were going to be trapped at home, we may as well enjoy it! It was ordered on May 7th, ad delivered on August 8th. It has been running now for over a year, non-stop, and through a mid-west winter.  We change the water periodically and stay up on the chemicals and it's done wonderfully. A great purchase that has served us very well!
