While it does work as promised, you will have to purchase another
While it does work as promised, it is not the last skimmer you will purchase. Water, chemicals, salt, and the elements will cause this product to disintegrate & fail. Getting any refund or replacement parts via email is a hassle, as they want pictures of the failed or broken part. They should simply mail you the part that breaks because it's always the same part. It's the "O" ring that goes around the base to ensure that the unit fits tight around the return opening that travels to the pump and filter. I am on my third one in 6 years.
