We purchased a unit for my dad who has ILD. We realized that the unit would not be sufficient as my dad is requiring additional oxygen support. We have contacted this company via email numerous times with bogus responses. The newest is they are on vacation. I am getting ready to dispute through my bank. The product has never been opened and we just want a refund. They say they will email return address instructions and never get anything. I would NEVER recommend this company to anyone. They are awful.

horrible customer service
horrible customer service. voicemail is full and they keep going round and round. they ask questions and you cannot reply as it's a 'do not reply' email address. I've gone round and round for several days on a unit that overheats and the motor runs loud. My doctor recommended this but I'm going to return it and find somewhere else that has good customer service. However since their communication is sooooo bad I'm not sure how I will be able to return it. I think I will file a claim thru my credit card.

THIS IS A LIE. THEY JUST SENT ME YET ANOTHER TIP TO FIX THE NOISE ISSUE. THE MAIN PROBLEM IS THAT IT IS OVER HEATING. IMPOSSIBLE TO REACH ANYONE AT THIS COMPANY AND THEY DO NOT HAVE A WORKING EMAIL ADDRESS. DO NOT BUY FROM THIS COMPANY

What terrible customer service, You sent me a device that you agree does not work and you state above that you were replacing the unit which was a lie. and now you want me to pay to ship it back to you while you fix it, All the while I am without oxygen, Yeah no, Try again to make this right, Keeping lying and I will keep posting the truth.

Great Product at a Great Price…
When the product arrived the Fail LED was on. Checke the Fuse- OK. Removed the Power Socket and found a wire lug was loose. Maybe got loos during transit. Reconnected and the machine is working perfect. It has made a great difference on my 100 year old mother diagnosed with Congestive Heart Failure wich causes low oxigen level. The unit performs excelent and it a great value. Got prommt support from manufacturer. Thanks

I bought the NT-2 based on a friend's recommendation. It's quieter than I expected and the buttons are really easy to use. It's powerful, detects my breathing, and gives me enough oxygen so I can breathe easily. The battery lasts a long time so I never have to worry about running out of oxygen.

Worst Customer Service Ever!
I purchased a portable concentrator from this company for my older brother that has COPD. By the time it arrived, I no longer needed it. I have tried numerous times to get the shipping address to send it back. I followed their instructions and emailed them the next day. I received a reply but no address to return the item. I again explained the situation, as it is still in the original packaging, and received another email offering a discount to keep it. Now, for the third time I sent another email requesting an address and no response within the 12 hours they state on their website. I’ve tried calling the two numbers listed in their website and no one answers. I would recommend no one ever use this company.
EDIT... I am now being asked by the company to take down my review and I still have not received a shipping address to return the item. So, far my opinion is only getting worse.

Convenient on the go oxygen!
The TTLife oygen concentrator has allowed me to get out more and be be more independent. It has a great shoulder strap and is light weight enough to carry.
