DuraTherm Spa Cover
Excellent 11/21/2013
Much better than my previous cover
I purchased a budget cover previously, and I always had to shut my hot tub down once the temps got into the 40s because it wouldn't stay hot enough. I thought for sure there was a problem (the hot tub came with the house, I've never owned one before), but I decided I should get a new cover first. Lo and behold it works amazingly. The temp stays above 100 even on the coldest of days (note that I live about 30 minutes from the Canadian border, so the cold is pretty cold). I suspect that this cover will pay for itself soon enough.
