(5) Five Cans - 95% Pure Oxygen - 60 Shots Per Can - Portable and Natural

My husband has asthma and we sometimes find the need to have extra oxygen for him ~ this is a nice product and is simple enough that the application doesn't break off as has happened on other oxygen can products we have tried.

It makes any different from just breathing air. No healing. No feeling any better. We still have 3 cans left and don't know what it can be used in other ways instead of throwing them in a trash can.

Doesn't work for me as advertised.

as advertised but no good
