I have never heard of a Pulmo Mate. If it works, I wouldn't see why you couldn't use it. If you just use it as a back-up or in case something happens to your primary one. I would say having it as a back-up would be better than having nothing at all.
I have had my Pulmo-Aide (Devillbiss) since 1989. It still works fine. I use it twice a day. I think I have only had to take it in once to get repaired. I must have lucked out and got a good one since everybody else seems to have had bad luck with DeVillbiss.
