Extremely unhappy with this company. They somehow found out that my husband was on a C Pap machine, they called our doctor who did give them a prescription for supplies. They called my husband who assumed it was our local medical supply company. The products did not work. He went to our local supply business with his machine because he was having so much trouble breathing. They found the c pap nose piece from this company would collapse on his nose so he couldn't breathe with it. This is a company that is taking extreme advantage of the medicare system and older people. Highly recommend no one buys from this company.
