works well it did not come with humidifier or connector hose needed to buy extra it would be nice if they told me but was good machine.

The concentrator runs pretty hot but seems to work well. The day I got it, I charged the BA-400 battery for a couple of hours and then tried running the unit while charging. I was VERY disappointed in that the unit shutdown on over temperature. However, I subsequently tested the unit with 3 fully discharged batteries and the unit provided oxygen while charging all 3 batteries sequentially without over heating even once and has displayed the same good behavior ever since. It does occasionally loose sync with my breathing but generally recoveries quickly. I suspect that the loss of sync is my own fault BTW. The clip on the belt pack is woefully designed and completely incapable of supporting the unit (even with assistance provided by the neck strap)! I still use the pack since I can't use the belly band (see below) but the unit is then free to swing away from my body and catch on objects or just bang into things. Also, I see no possible way to install the unit into the provided belly band. I don't know yet if I am just 'missing something or if this is the wrong band for the unit that I purchased. While it is louder than I would like and much louder than bottled oxygen of course, it is also much lighter and convenient to use. Disclaimer: I do NOT have experience with other brands of concentrators so consider that in the following statement: Based upon my experience in actually using this unit, I do recommend that people consider this unit when looking to buy a portable oxygen concentrator.

The reconditioned concentrator works great, but it took 7 days for the concentrator to get from the factory to Fed-ex.

Shipping took too long. It came runs better than the new one I bought for reconditioned. Would be 5 stars but was not satisfied with shipping not sure of who was at fault. Would recommend them to anyone and will go back in the future.

They were a little slow on the shipping. I wish they posted the hours the machine had been used on the info. I would have spent more to get a newer machine. So far it has worked well.

Delivery was a little slow. Unit worked for 2 days and then failed. Called to report the problem. Repersentative was very nice saying they would send out a new unit. That was on December 26, 2018. Have not received the unit so far.

Concentrator arrived damaged. Called and they responded quickly and gave me reasonable assurance that the damage is cosmetic, but the unit functions properly. The shipping company beat it up pretty good.
