Bests & Worsts Reviews from Amazon

I read several reviews before buying that made not want to buy this product. After purchasing the product and installing it, I really have to doubt those reviews. It is an excellent product and performs exactly as stated! My pool stays around 80-85F. I have a timer on my circulation pump for 15 min on/off. I turn the pump on around 9 am when the sun hits the heater and off when the shadows fall in the afternoon, 4pm. I did have to buy 2 hoses to connect it, but that makes sense when you think about it. The mfg has no way of knowing how you connect!
