The portable O2 concentrator is heavy and bulky to carry. I don't like the intermittent O2 vs continual O2. This machine isn't as good as a previous one I've used. There can be a lot of improvements made to the portable O2 concentrator to make it more user friendly.

The pop corn sound. Is heavier than told8

Too noisy. Batteries don’t last as long as advertised.

I have not been able to use the machine. It doesn’t work properly.

Customer service & after purchase assistance is excellent. The battery life is much shorter than quoted. Quoted was 2:15 for the small battery. The best I can get is 1:45. This is sufficient for most of the time.

I really haven't used it that much. My breathing is better

they only thing i have to say in not a recommendation more a comment when buying this unit I thought it came with a charging system. You need a portable charging system to charge the batteries because it takes so long to charge. It cannot use the machine. You only have two batteries and a well 2 to 3 hours to charge up the battery so you oughta have a portable charging station separate from the unit. And no, I am not getting as much comfort out of the unit as I thought I would. I am not totally disappointed, but I’m not jumping up and down for joy and either thank you Austin Kyles.

After doctor approval, I ordered the Inogen Rove 6 April 25th for my father with the backpack. The backpack never arrived after receiving the Inogen. On May 20 when I called customer service and explained the 1st Inogen didn't function correctly, they sent out a replacement. I also reported we didn't receive the back pack and she said she couldn't help me and that I needed to go back to my salesperson. In the purchase process of the Rove 6, Scott was very helpful. I emailed him too on May 20 explaining we had not received the back pack. The sling was too heavy for my dad's shoulder and he couldn't use the Rove 6 for walks. After several emails, we received the backpack on June 10th. My dad loves the 2nd Rove 6 and the back pack but the process to get a functioning product and the back pack wasn't easy.
