My old Phillips conked out on me back in Oct. 2019, a month b4 I was to move to Albuquerque from TX. American Home Patient said: "oh, yes, lot of those are bad. I can switch you to a new one, but they are out of stock." I said that I leave in 3 weeks, she says no problem. Never heard from them again. Covid hits months after I get to NM, my machine is on the fritz, and I don't know how much longer it will keep working, as it shuts off once and awhile. I decide to sign up for my VA benefits; end up getting a new ResMed one which works fine. Have had it about 4 yrs. Fingers crossed. carry on
