Although I initially had problem placing the order (problem with address on credit card)for CPAP machine. The problem was solved and the order went flawless. The delivery was on time and very fast. I'm extremely happy with the new CPAP machine and it exceeded my expectations. Very happy to be rid of my old loud Phillips machine (still waiting 1½ years for them to replace it on the defective devices recall) I can now sleep better knowing I'm not using a CPAP machine that could be poisoning me with toxic gasses and cancer causing particals. I look forward to doing more shopping with cpapxchange as they have met and exceeded my expectations 100%
