Inogen One G3 Easy Fix
The column replacement was beyond easy. I spent about 15 minutes on the task including opening two boxes. The furnished tool is awesome in its simplicity. If I can do it (82 years old), anyone can replace the cylinders with ease. Good work Imogene!! Hank C.

2nd purchase satisfaction!
Came on time, with easy to see/read instructions for removal of old and installing new ones. They are not a ‘generic’ brand, they are Inogen parts!

Original fit
Original replacement columns as best I can tell. Actually arrived one day early which was nice. Only problem was one of the duct caps had fallen off but i installed it anyway. It appeared to have come loose during shipping but it was a clean wrapped packaging so I felt pretty confident about it unless somebody can say don't use it and give me a valid reason why not to.
