Holds up in the freezing cold

We got our 1st substantial amount of snow for the season {3 Feet} and I swear our Barefoot Hot tub Is just like the Energizer Bunny , It keeps Going and Going and Going! I live on a mountain top {5,200} ft. elevation and was a little leery about buying another hot tub after my old tub Froze and broke. My Friends live in the Colorado Springs Mountain Range and they recommended me buying a Barefoot Spa because of the great luck they have had with there spa in FRIGID temperatures. I recommend Barefoot spas to anybody living in a Extreme Cold Temperature environment.
