I had a miserable experience with this company. i had a high deductible, and ended up having to pay their inflated and unreasonable fees. for example, they billed me for a part of the CPAP device, the humidifying chamber, separately. I ended up paying at least $250 for a small piece of plastic. if i had done some basic research, i would definitely have gone elsewhere, but my sleep doctor's office recommended them. my usual company wasn't willing to authorize the device that i needed, which explains how i got into this nasty situation. Of course, their marketing person is very persuasive. At this point I convinced them to recommend other suppliers, but unfortunately, it's too late for me. this company had to pay a fine of $29 million (!!!) to Medicare due to over charging the government. why they're still in business is a total mystery to me. well, maybe not - they must have paid off somebody. Do yourself a big favor and STAY AWAY!!!!!
