I have been using CPCP Clinic for the past 6 years (4 times a year on average) and constantly received great products (with great warranties) along with excellent service. I've always had a great experience each time I dealt with Alex and his team. Alex truly cares about your needs and he goes out of his way to make sure you are satisfied. I find the prices to be very good and the shipping is very fast as well. I definitely recommend them for any of your CPAP supplies needs.
