Ordered a Freedom CPAP battery from them ($278) after reading the battery would last 6-8 hours. During purchase, I asked if I had any trouble with the battery should I return it to CPAP.Com or the manufacturer and was told CPAP would handle any problems and that they had an easy return policy.
Tested the battery twice and it lasted less than 2 hours. Tried to return the item and was told by CPAP.Com Customer Service that since the item was opened the return policy was void. They sold me a product that did not perform as promised and lied to me during the purchase process to complete the sale. I would recommend taking your CPAP business elsewhere.
