Don't waste your money. I've owned 3 of these devices, all died after 2 seasons and I did maintain them as prescribed. That is 2 x summers, aka 6 months total operating time (1,400 hours). They work OK but wasn't made to last and if you call support after 18 months, they advise you to buy a new one. I initially convinced my neighbor to buy one too and they experienced the exact same thing. I will never advise anyone to purchase this product unless they feel that is an acceptable lifespan/return on investment. No more Intex for me thank you.
