    It's a pleasure to get the exact matching product for my machine. NOw that my CPAP machine is no longer made I was worried the replacement water chamber would not be like the original therefor it could cause problems (not fit exactly, leak, fall apart, etc). This one from cpapXchange is the same one as was on my machine before. The service was really quick too, I received the new water chamber in just a few days.
