Product review (1 stars): Output Amperage doesn't match
I have an M-Series RemStar - and the output amperage of my original power block is 4.18.  This power adapter has a 7-8 Amp range, which causes the machine to shutdown once you start breathing.  This is not a compatible replacement as stated.  Stick with the Philips product replacement.  Also, the company is very difficult to handle returns, I've referred my return issue to the MasterCard credit card company to handle.
