Reliable and worth the money
I have ordered the columns 3 times to keep my Inogen portable oxygen machine working. It is a lot cheaper to spend your money on replacing the columns then to purchase another unit. I do use the unit more then before, if I leave the house it goes with me. The price is good and the cost for the columns hasn’t increased that much in the 8 years that I have had the unit.

Don't last very long.
These replacements last about a year. I don't use my oxygen all the time, so for the cost to replace them I think that's rediculous. But this is one of those things you have to replace so you are kind of stuck. They are not any cheaper getting them from the dealer. Your insurance might cover them for you, but mine does not.
