  1. Much better than conserver tanks

    Posted by Gerry on 7th Jun 2018

    I have had the G3 for a month, and am very pleased with it. The one week trial period was adequate to evaluate it. I was concerned about the sound level which I initially found higher than expected. I now consider it to be just fine at a setting of 3. Working with Jeff Dewberry was a very good experience, and after a lot of research I believe that Portable Oxygen Systems is the best place to buy this device. The price is several hundred dollars less and their service reputation is great.

  2. Very good

    Posted by Robert L on 26th Mar 2018

    Unit is great. I play a lot of golf and looking forward to getting out to the course.

  3. Great Portable Concentrator

    Posted by Unknown on 6th Mar 2018

    This is by far the best portable I have used.

  4. Replacement unit

    Posted by Unknown on 26th Feb 2018

    Well pleased with this unit--it replaces a different make that had an 8 cell battery. The G# certainly performs as advertised. Having only had it a short time, I do not yet know about dependability, but think that it will be as advertised.

  5. I LOVE this Oxygen Concentrator

    Posted by Grizz on 28th Jan 2018

    I liked the G3t so much that I bought a 2nd unit as backup in case one breaks down. I was fearful of going on vacation without a backup spare.

  6. Best Price I could find

    Posted by Eddie H. on 17th Jan 2018

    I am happy with the G3. It has proven to be a very good machine that works well for me and how active I tend to be. I got great information from this company and I got the best price.

  7. Reliable POC

    Posted by Harvey T. on 9th Jan 2018

    I have used this machine for a few months now and it's proven to be very reliable and easy to manage. I travel, I work, I play golf and I couldn't do these things without my G3. The long battery life works out great. I got a great price and great service from the folks here at Portable Oxygen Solutions. I am happy with my choice.

  8. Super easy to use

    Posted by Mike E. on 31st Oct 2017

    I really like this portable oxygen condenser. It has allowed me to go and do things I used to. I am traveling to visit my family for the holidays this year for the first time in 4 years. I'm so excited. Jeff, thank you for helping me, guiding me and ensuring I got the best model and the best price I could find anywhere. I recommend anyone reading this review give these guys a call. You will not regret it.

  9. Simplicity of use

    Posted by Unknown on 5th Jul 2017

    Like the weight, convenience and length of charge. Has allowed more independence and exceeded expectations.
    Only negative is would like the print in instruction booklet to be larger as had difficulty reading it.

  10. Great Price

    Posted by Joseph T. on 29th Jun 2017

    Thank you for helping me choose my new Inogen G3. It works great and the 2 batteries really allow me a ton of freedom. Best service I received from anywhere and you saved me several hundred dollars. I'm very satisfied. Thank you for being a great company that cares.
