Your service is awesome
Your service is awesome. I can’t say the same for the US Post Office. You answer questions quickly. Your prices are really good. And the quality is terrific. We’ll be back if we find we need anything else.
Worst company I've ever dealt with
Worst company I've ever dealt with. This company cannot be trusted as they are scamming people. I ordered a machine on the 29th of April and they only sent me accessories and not the machine. I've sent dozens of emails and called asking to cancel my order and they keep running around in circles. I highly recommend you stay away from this company

Love my NT-3
The portable oxygen machine works great, very light and easy to use. I purchased the extra 8 cell battery and I'm glad I did so I can spend more time outside and away from home.
