DO NOT BUY!!  DEFECTIVE!!
Bought mine from a medical supply store for $100 more than amazon. I would have been happy but my leg is swelling up after ACL surgery because the heat is running while on cold setting. This causes the ice to melt fast and it is coldest for about the first ten seconds that it’s turned on. It is wired wrong or pump is overheating so much that it warms ice cold water.
