Very good company Very good company. I highly recommend the Varon machine. Quiet and I only have to use setting 3 to get my oxy level up Don't worry about negative reviews as they are inspired by competitors. DB LAWS MILFORD

Price,quality Price,quality, and customer service made this one of the best purchases I've ever made, and I am 92. My needs may be a little unique in that I have congestive heart failure but normal ecgs and echocardiograms. They put me on oxygen. Living in a flood zone in an elevated house meant needing help getting up and down stairs . I was looking for a portable rechargeable oxygen generator to give me more freedom. No help needed. After careful investigation I found the NT 05. From the moment I opened the box and saw how carefully it was packed I realized I was getting a quality product. The instructions were clear and it was easy to get it ready for testing to see if it met my needs. NO problems. It now gives me the ability to come and go as I please. The battery easily lasts two hours so I don't have to worry about it shutting off (4 hrs with the back up battery). I looked at a lot of generators, most cost hundreds if not thousands more and did not have the same features. The customer service was great, the same quality as the product they sell.

Dealing with COPD had me stuck at home Dealing with COPD had me stuck at home, feeling pretty low. Then I found TTLIFE’s oxygen concentrator – it changes my life! It's lightweight, quiet, and doesn’t break the bank. Now I’m back to enjoying walks and shopping without worrying about oxygen. Big thumbs to TTLIFE's customer service – you guys great!

TtLife and their policies TtLife dealt with me over an Oxygen Concentrator I purchased. After I received the device i talked with my Pulmonologist. He decided the concentrator was not what I needed. I emailed with TTLife and they were wonderful. Offered me an even trade for another device. I decided to go a different route and ordered what I needed. TTLife agreed to let me return my device and to refund my money. I returned the device and I received my refund within 3 days. I highly recommend TTLife for your purchases. Neysa McFarland
