Welcome to our forum.
I've been using Doc's blanket for the past few months and I've been pretty pleased with the results. Though I haven't measured electric use, I will go out on a limb and say it definitely must be saving money. The 1/4" blanket does not bunch even with all jets on high.
Hey Tony, how difficult is that blanket to handle getting in and out of the tub? Â That was the only reason I hesitated with it. Â There's nothing worse than wrassling with a large piece of wet plastic in the winter.
