Mike Neylon
Mikey's G5

I was upgraded from G3 to G5. I went kicking and screaming, but it turns out he was right and I was WRONG! I love the G5 so far, (still in the honeymoon phase) and the battery life is as good or better than G3, as predicted!

David Kornbluth
Extremely Happy!

I was in need of a portable machine that didn’t have propane tanks,as I was flying to NY for vacation.The new ones were way out of my budget.I called around and inquired about used machines,and did not have ANY satification with anything until I called MajorCPAP! When I called they said “sure we do!”,with no upselling to a new machine! I listened to what he had,upgraded my battery,and purchased a warranty and it was shipped.When I received the unit,you would never know it was preowned. Everything looked new,complete with manual,receipt,charging cords.I would send ANYONE looking for a preowned machine to check with MajorCPAP,and you will not be disappointed in any way.
