TTLIFE Reviews 

My items are wonderful and the process to order is very easy.

Unit was delivered on time and easily set up. Concentrator is very, very quite. I've logged over 50 hours and its does great.

I was sent a tracking let me know when to receive. So far I am very pleased with my item. Note it did not tell me about the connection for nebulizer. Found it on the internet.

I love the lightweight of the machine and it works very well. I am new to this technology. This is my husband's oxygen machine and we used it for the first time last night; when the battery quit he didn't realize that he wasn't getting any more oxygen. Some type of alarm would be great so I knew when to connect the other battery.

We purchased the NT-8G oxygenator and, subsequently, a second battery. We're very pleased with the unit, and it suits our needs perfectly. It's compact, easy to use and we purchased it because the oxygen purity is 93% +/- 3% at every setting - 1 - 8. When we're out shopping or visiting family or friends, we set the unit at 4 L/M. Unfortunately, at this setting, battery life is about 2 hours. We purchased the 2nd battery to compensate for this. The DC power charger keeps the battery level at 100%, but when out of the car for an extended period of time, the 2nd battery gives us the time we need. I would recommend development of a 16 mh battery, which would make matters more convenient. Nonetheless, this is minor matter which is overcome by the convenience of use and the high oxygen purity levels. I highly recommend the 8G to anyone in need of reliable and pure supplemental oxygen.

Concentrator didn't meet my oxygen needs. TTLIfe advertises continuous flow at 93% +/_ oxygen cocentration. However, it does not make it clear that is ONLY at 1L setting and goes all of the way down to the 20-30% oxygen concentration range at any other setting. They advertise easy returns. NOT TRUE! Buyer beware as the only way to receive a refund is to return the product to China and buyer pays the shipping. I was quoted $598.00 to ship the product back. I paid $596.96 for the concentrator and extra battery package and did not use any of it. TTLife would not accept the battery package to be returned so the shipping was for the concentrator alone. Emails to customer support were not returned for days and were worded in a way that would require several more communications to get any kind of answer to my questions and the return policy. Pretty clever as they only offer a refund within 30 days and they use up several of those days for communication. Company offered me $70.00 to keep product and suggested I sell it instead of giving me 100% refund. Eventually, customer service offered me only $130.00 for a machine that is absolutely of no use to me and suggested I try to sell it to recoup the difference. The fact it only offers 1L for 93% oxygen concentration makes it a machine very few, if any, will buy for that price. Very deceptive advertising ! I am wondering where the good reviews come from. BE VERY CAREFUL ABOUT ORDERING FROM TTLife!! I'd look somewhere else and stay away from buying a concentrator from this company. They ship from warehouses in the United States but returns have to go all of the way to China!!

I love my o2 machine. Battery only worked an hour. So that could improve

My oxygen concentrator was shipped quickly! It is easy to use. It makes me feel relaxed and refreshed.

I was able to go on the site and easily find the machine that would work for me since each item had a complete description of what you could expect from each device. Even though the prices are already reasonable, they also have really good specials and discounts that bring the price down even more. They let you know what will work best for your needs. The Customer Service is really good, and my orders have delivered very quickly.

Shipping is a problem. They say my item was shipped by UPS. UPS says no it wasn't. I am oxygen therapy dependent and I need the machine I ordered. Are they for real or are they fraudulent? Where is my order?

Very nice concentrator, I slept great my first time using it, it is so nice to have my oxygen at night, now I can’t wait to receive my portable… Fast shipping n very friendly customer service…

I needed more oxygen than my inogen one G3 could produce. In a side by side comparison on both level 3 and 5 the two machines matched. The Varon does go to 7 and it seems to be working great. The battery actually lasts longer than the inogen does.

This is the quietest unit I have ever had.

I have purchased 2 units so far from your company, nt06 and recently nt 04. I am totally pleased with both units and use them daily when I go out and when at home. Both came with everything you need, nothing extra to get. I initially had trouble with the battery on the nt06 not charging properly and you resolved the problem and replaced the battery promptly. I can say nothing but good about your products and service and highly recommend your firm. Finally I must say you will not find a better price on a quality unit than here.

I bought a home Varon Oxygen concentrator. It is quiet and with IPB, it gets my blood oxygen to 99%, sometimes 100%, while setting watching tv. I’m impressed. And the price was the best I could find. This unit is heavy duty also.

Reasonable priced and so far, working very well. I own 2 and ordered a third.

The ordering and shipping process was easy and fast.

You have not shipped my order and it has been almost 2 weeks.

The Machine is very flimsy and not sturdy. Needs 110 voltage cord and not phone charger port. Carrington bag doesn't have a port to plug it in. I should have done my homework and bought a better model.
