Customer Reviews

GoodKnight 425 Bi-Pap

I no longer have insurance and my old machine had stopped working. Looking for a better priced option, I found your web site and this unit. I ordered it on Tuesday afternoon and it was delivered to my home Friday afternoon. Outstanding service. The unit itself is smaller, quieter than my old Respironic model. Over the past ten years I have had two Respironic units brought by the insurance company and this unit to me is superior to those. I am anticipating a favorable relationship with your company. Just remember you have set a high standard. Thank you for your rapid service to my need.
