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 2

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.

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

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

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.

Good well made help the wife imensly

Good for handbag. Good price.

Made no difference to me at all and only lasted for a few puffs. I won’t be buying again.

It really helps straight away. So easy to use and very useful. Thank you so much
