Boost Oxygen Cylinder Natural Flavour 3L Pack of 3 | Portable Oxygen Canisters | Lightweight Oxygen Cylinder for Breathing,Hiking, Sports, Outdoor & Active Lifestyle Use | Up to 180 Inhalations

First time seeing the "pocket" version - portable and very useful for sports, altitude, humidity, poor air quality, especially if there are underlying conditions, which are not, however, severe enough to require a 24-7 oxygen tank! Also smokers - but keep well away from the "lighter!!!" Discuss with your physician especially if you suffer from asthma or anemia. May be helpful there too.

I deal with cluster headaches and the attacks come in very extreme each day that goes by I realize I was getting more in a day as well hopeless going on everything for research just to take the pain away I tried everything and nothing so I saw something taking about this so I thought why not give it a try I didn’t think it would be that great my attacks can last for hrs sometimes getting some back to back and when I tell you gone in 15 maybe 20 mins it was gone so quickly if you or someone you know is dealing with cluster headaches highly recommend this they are small pocket size but it does work and it relieved my pain and I think it was worth the money small or not it was just a test run and it works.

Excelente producto, te sorprende un poco cuándo los ves por que el tamaño de la botella es muy pequeño, pero es super eficiente recomendado al 100 %

It’s empty

I got these for my husband who has cluster migraines. He had one tonight and used some of this O2. Seemed to help. Will buy more. I bought the 2 pack because I wasn't sure if it was going to work. Seemed reasonable. The cup fit his mouth well. Was easy to use even with a migrain. Did not complain of any taste or smell.
