Excellent service and delivery of a very good product.

My concentrator has been working very well so far. I’ve had about a month now and have had no issues or problems with it whatsoever. This machine was a great value for the price. Thank you, Roy E White Sr

I purchased a Varon NT-06 from TTLIFE on Sept, 23. I received it a couple of days later. It was supposed to provide continuous oxygen flow but it doesn't seem to deliver any oxygen at all. I used it twice. I contacted TTLIFE to request a return but they keep giving me the runaround. The same guy answers the phone and tells me that they have to contact the engineering department to initiate a return. He asks me to take a picture of the unit and include the Model # and Order #, and a brief description of the problem. 2 days later, I receive an email asking for the same info. This continues to go on for days and they will not give me an address to send the machine back to them. This is a SCAM Company and the guy running the SCAM should be prosecuted.

We’re very sorry to hear about your experience. We completely understand how frustrating this must be. Please rest assured that we are a trusted store, and this seems to be a delivery issue with the carrier. Could you please share your order number so we can check the details and help you resolve it as soon as possible?

I ware a CPAP device at night and TTLIFE was the only company I could find that has a portable concentrator that had continuous flow to attach to my CPAP and use as I travel. I have just ordered a home oxygen concentrator to use every night and return my rental unit to save on a monthly charge.
