Review (1/5): pass it up...it's cheap junk
Older reviews mention the hose was a good quality by respironics. NOT SO any more! This hose is cheap, somewhat smelly plastic, and too stiff to use in comfort on a cpap machine. The bag it came in says its from American-Bantex. The original hose that came with the cpap is much, much more flexable. I tried this one night and got rid of it.
I'd recommend looking elsewhere to anyone looking for a new hose for cpap machine. Jim
