Hi Boost O2 Oxygen in a can 10l Each can Total 30L (3 Cans) Portable Oxygen Including 1 x Mask and Tubing Set - Great for Sport, Work, Health, Increased Concentration and Energy - Made in The UK

Ideal for a quick refresh after exercise or if you are feeling breathless. Not to be confused with medical grade Oxygen. They sometimes come empty and it is wise to save the push down button as now & again, they do not work. Worth buying though as faults are few and far between.

Bought this and one tin was absolutely EMPTY!! Now if you buy 3 tins and one empty you gotta wonder whats in the other two!!

Great value for money thanks

Was taken back at how quickly these depleted....use sparingly

all good

Easy to use

a great item for people that need oxygen from time to time

i am sorry but these cans hold nothing and run out absalutly useless have felt no effect and waste of money will not be buying again , do not buy
