I apologize for the inconvenience, Dan. Accuracy in product information is important to us. If you have any concerns or need further assistance, please feel free to contact us. We're here to help.
I dislike the short battery life, 2.5 hours max, with a standard battery, and a setting of 2 Lt. In my opinion, that's pretty short. I've only had it for four days, so far as the concentrator itself, it seems okay. Not thrilled, but that's as good as I can expect.

We appreciate your feedback, John. It's important to us that you're satisfied with your purchase. The battery life of portable oxygen concentrators can vary based on the device's settings and individual usage patterns. While the standard battery life at a setting of 2 may be around 2.5 hours, we do offer extended batteries that can provide longer use times between charges. If you're looking for longer battery life, this might be a solution worth considering. Our team is here to discuss any concerns you have and explore options that might better meet your needs. We aim to ensure you have the best possible experience with your Caire Freestyle Comfort concentrator.
The ordering & delivery of my new Sequal Eclipse 5 O2 concentrator was well handled. But the policy of not notifying me in advance of sale about the very short-term return policy deadlines -- combined with the later admonition to me when I questioned my machine's performance ("Run it for 100 hours before you can tell if it is working properly") -- was unfair at best and a questionable business practice.

Fast shipping but almost $20 to ship two tiny foam filters for my portable oxygen machine. They could have been mailed for much less.

I was billed for the machine then asked for a prescription that I did not have readily available. It delayed delivery for two weeks.
By Smith, R.

The purchasing process went extremely well. However, when I got the unit home and received the invoice realize the invoice was written to Mary Schröder at our address instead of my name. I then sent an email asking for a corrected invoice for my records, but have yet to hear back from anyone.

A member of our team will be in contact with you today to ensure this matter is fully resolved to your satisfaction. Thank you for bringing this to our attention, and we appreciate your patience as we work to sort this out.
My new concentrator did not work. I was excited to begin using the GS4. However it would not work and I will need to wait for a replacement.
