PHI haven't used my concentrator yet but… I haven't used my concentrator yet but the service I got from Nick was outstanding. So far the service experience is great. Hopefully, the same is true about the product.

GBA bit heavier than I thought but… A bit heavier than I thought but tolerable. Came a few days sooner than expected which was great. Easier to get from point A to Z with less energy used. Great little machine.

GBHelpful and easy, made in the USA I looked on line for several months before finding the O2 concentrator that would provide what I needed at a price I could afford. A representative then then helped with and kept me informed of the progress. It was simple and easy which was greatly appreciated in this complicated world. Best of all the company is located in my home state and to product is made in the USA.
