Lymphoedema Pump

I rented it to try for 3 mths, under guidance of a therapist. i didn't think it did a lot for the time it takes getting set up to lie  flat on floor so , emptying torso,clavical,groin lymp pits  ,deep breathing  pre sequence, then pump sequence. ( adds up to about 1 hour)  I can get more efficient reduction and seems easier using a small roller ball and  various arm movement,exercises, tai chi,overwraps etc. I will save it for when i  get older or sick and less mobile.
But I also know lots of lymphies that love the pump.
