Absolutely awesome! I received mine about 2 weeks ago and I am kicking myself for not having done it sooner. Yes it is pricey. I live in Las Vegas and plunging in the summer was problematic with my Ice Barrel. The chiller holds it at a steady 55 degrees and it’s June, when our average outside temperature is around 104. It is truly plug and play. It took me about 15 minutes to get it up and running. It’s pretty quiet, and cleaning the filters is easy. The design is genius and no drilling is required for the 400 style barrel which is not the case if you buy a chiller from the manufacturer of the barrel and they don’t even have them for sale yet. I also bought the insulation wrap as my barrel isn’t insulated. I am super impressed with both items! Highly recommend!
