Nice filters, ordered 10/03 received 10/19. Price was great compared to ordering from manufacture. Package spent more time in customs than in transit (can't blame the company). Will order again if needed.

I originally ordered my unit so that I could have something to take with me to go visit my sister and I just tried it and made sure it worked and it did. Thank you then this morning my main oxygen concentrator quit working and it was so nice to have this unit to fall back on and it worked beautifully. Thank you.

The equipment came in as predicted. All in good order. the concentrator is terrific, it works very nicely and it is relatively quiet. I need to use it while sleeping, so it is very good.

Great product, size, weight battery life. You can make the case a little bigger to store the chargers ( ac and 12 volt) spare cannulas, filter etc. Alcohol wipes for cannulas. Not just a few spare batteries. Airlines want 150% battery life for trip.
