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!

No working phone number No working phone number. I paid for a machine and it is lost in the mail TTLIFE has done NOTHING to resolve the problem. They refused to return my money or ship another machine. TTLIFE blames the shipper yet they will not give me the name or phone number for them. RUN don't walk away from this company.

Order oxygen concentrator December 23… Order oxygen concentrator December 23 2021 received following week damaged. Contacted ttlife several times and sent pictures each time as requested. Now end of March 2022 and told replacement time is expired. I am screwed by another Chinese company.. never order directly from any foreign company. I will always go thru Amazon they have instant refund or replacement. TTLife sicks big time.

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.

model NT-05 I recently purchased the NT-05, and it works for me. Its compact and lightweight design makes it incredibly easy to carry, especially when I'm out walking my dog. It's a significant improvement over the bulky machines I've used before, offering convenience without any fatigue. Highly recommend for those seeking a portable solution!
