Machine portative à oxygène 3L - Générateur d'oxygène à deux batteries avec concentrateur d'oxygène portable avec sac et ensemble complet d'accessoires (deux piles)

I am so shocked ! I had to purchase mine due ins not paying for a rental. I got calls daily for the expensive ones (3000 to 4000) that I could not afford so I got this one and man I charged the batteries and used it right away. The oxygen is strong no liter numbers but it helped alot. I am very happy I picked this. I did get a extended warranty and it is my first day but fingers crossed this will be exactly what I need.

Works wonderful and light weight which is a bonus. Thank u!!
