I live in west central Wisconsin with a large amout of woods and about 600 feet of frontage on a creek with a pond. Our spa is out side built into the deck. We purchased a Coleman Misquito Delito at Menards for about $150.00
It works GREAT. they claim the propane tank will last 30 days. It's more like 90 days. I am 100% sold on this product. It's a win win deal.
