I needed a travel cpap machine very quickly to go with me on a deployment for the Red Cross. I was advised about a particular machine. I paid $50 for overnight shpping. When it arrived it was heavier than my regular cpap machine, with equal dimensions just vertical instead of horizontal. I had told the salespersons my need for low weight but she recommended this anyway. They have a 15% restocking fee. Then they sent it to the wrong address. When I explained that it had been misrepresented, she agreed to a 5% restocking fee, but would not take away that charge. It was sent to the WRONG ADDRESS, so I did not get it the next day, as paid for, but had to finally track it down and go to the post office to get it. They would not refund the shipping, and when I asked to speak to a manager (the owners) I was told they would call me. I have since left 5 messages but no return call. Its been six days now.
