Esay, Informative, Amazingly Quiet Product
One email to Katie Y., who I had previously bought a portable from, and I had everything I needed. She had the information I was looking for and the stationary unit I bought (DeVilbis 5L-Q for QUIET) is whisper quiet (even compared to the non "Q" model ). Shipping was fast and the unit came with everything I needed. This is my "go to" for oxygen concentrator information and product.
