The battery could last a little longer
By Annabell K.
Good product as described. Fit into the space nicely. Great price point.
By Allen
The quality of the goods manufactured and sold by TTLIFE are very good and I am happy to own my home O2 compressor. I was less impressed by some of the assumptions made by their sales representative who misread my saying I would purchase a different model and wait for its receipt before proceeding with a requested return of a model inferior to my oxygen needs. We worked past this, but the incident was upsetting to me and no apology was ever forthcoming from the unidentified agent.

Having continuous air flow is exactly what I need. The insurance gave me a pulsater type machine, which is not good for me.

Still waiting on 2nd battery, should have been delivered with order.

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.

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