God sent for some one like me less lung capicity due to a terminal illness. When needed especially in hot weather. I will recommende it

I had a cold and needed more oxygen as my oximeter readings were in the sixties and seventies on and off and I was very breathless. I wanted to avoid hospital so purchased this and it did the trick.I understand that mountaineers carry them for when there is little air I also learned that it is good for a hangover the following day! Eight deep breaths and hangover gone! I don’t know if it works as I don’t drink much so never have a hangover. Warning don’t over do it for it isn’t healthy. Buy the oxymeter and keep your eye on the readings and stop when it reaches 94 and above.

After initial disappointment with product, the seller sent out a replacement with different nozzle. This replacement appears to work. Will try for a while & report back.

the button is really hard to press and doesnt even work

Great company! Well worth it, will buy again. Minor problem with one canister speedily replaced! Most satisfactory.

After just one day the flow of gas disappeared. For £30 one day of use is totally unsatisfactory. Found it a total waist of time, effort and money. Be very wary of buying this product. Update: after discussion I was given a full refund for faulty canister. Firm was very helpful and obliging regarding this. Updated review to 3 stars and will retry if they update design of the canister valve.

Good price, very fast item delivery. No indication of the best way to safely recycle the canister in the U.K.

Fantastic Customer Service from Matt at Evolve - I had a problem with my order needing quick intervention and he was quick to act and really appreciate how supportive he was. Grateful for the help and will definitely use again. So far the canister is working well.
