EVOLVE 15-Litre Pure Oxygen Canister with Breathing Cup | Portable Oxygen Can | Ideal for Home Use and Outdoor Activities | Designed by Firefighters | Made in Britain | Pack of 1

Great product I have used it in very short bursts (1-2 sec) 7 times now and it still has oxygen left. Remember to only pull trigger when breating in (otherwise you're wasting it) I do an inhale then hold then breathe out method when using it. I believe it has helped some of my headaches and recovery from migraines (only marginally but anything is better than nothing) its definately a luxury item but if you have the money and are looking to buy oxygen in this format get this one.

Really good and does exactly what I need and has given me peace of mind that it is available when I really need it. Only dropped down to 4* because I feel the breathing cup could be made of a softer more mouldable material to provide a better seal during use.

This product is very helpful for my husband who has emphysema. Easy to use and carry around. I've bought two more larger ones. Great value

Great product great design but very expensive for what you get they do not last long I will not buy this again for that reason was very disappointed how ever I have given 3 stars for design, ease of use, and could save a life.

Didn't notice any difference from using it, seemed like a waste of money

If you get out of breath a few puffs will help you ,it's light and easily goes in your bag.try it its clean air

THIS IS EFFECTIVE FOR GIVING YOU AN EASY WAY TO BREATHE AND FEEL FITTER

My Grandmother is on palliative care, and when she has an anxiety attack, these really help her. They also help when she’s lightheaded.
