First time customer
I was more than a bit leery of ordering online despite your excellent rating & reviews. I was very pleased with John who was non-pressure, and patiently answered all my questions & concerns. Received the extended battery for my concentrator timely. The only disappointment is the "noise" (which has nothing to do with you).
