Wow, this is an Amazing Product. It was Easy to set up. The bubble jets are as strong as from a large Hot Tub. We set the heat at 103 and after opening the top and enjoying the Nice Hot Water, with temps 42 outside, we are able to enjoy the soak for a couple of hours before it cools down to 100. Sadly the cost of heating was high. We are hoping that in the summer when the weather is hot, we will be able to enjoy without it having to keep running the heater. Great product and so well made!!! If you have solar and can afford to use this in the winter, you will LOVE it. We are going to drain ours now until the weather warms up in the Spring. The Floating Frog for clean water is amazing.
