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.

Bought these for my husband who has emphysema & COPD. His oxygen levels do not entitle him to Oxygen provided by the NHS so after research found these 15 Litre Evolve Oxygen canisters which are so easy to use & uncombersome to take along when going out. Breathe Simply Limited are second to none with their After Sales Service so our heartfelt thanks for such a great product & exceptional service.

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.

After doing some research on this product and placing the order, the item was packaged well and arrived quickly. This product will come in handy in the gym and also on some upcoming ski trips. Easy 5 Stars From Me ⭐️⭐️⭐️⭐️⭐️

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

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