I love the spa for the convenience of having been able to shop online and have it shipped which is hard to get since most spa stores make you visit the store and I live in a rual area. However, I also live next to a huge river close to Colorado and its cold outside so the small pump and low wattage has made it almost impossible to get the unit up to temperature. It has been on for almost 2 days and its only up to 90 degrees and that is after I completely enclosed my porch with curtains and blankets.
