Columns for Inogen
I bought this in April 2023. It seemed to be working fine until a couple of months ago. My inogen screen is flashing change columns. I was hoping I could maybe get another year or two out of this. Otherwise, worked fine.

Comme c'est l'hiver, l'emballage ne comportait AUCUN isolant. Aussi les colonnes m'ont été livrées très très froides. Par précaution j'ai dû les laisser reposer 48h à la température de la pièce avant de les installer.

This item is for a piece of a oxygen concentrator. This concentrator is to keep you breathing as keeping you alive. The reason for a one is that after the installation it didn’t give a success answer. Now if I use this concentrator I don’t know if it will work properly.
