Oxygen Plus – O+ Biggi 2-Pack | 99.5% Pure Canned Oxygen | Energy, Endurance and Recovery | High Purity Oxygen | 50+ Uses Per 11 Liter Canister with Mask

Didn’t specify the fact a mask was needed, but I improvised with one I had already, problem solved.

Did not realize they needed a mask. Otherwise great

Delivery was much quicker than expected, however, this product was unusable as trigger mechanism did not work on both of the bottles. Very disappointing. Company did refund immediately without the need to return, however would have been much happier to receive a usable product

Either didn’t work or were empty. Rubbish

We have used this brand before and it was very good for my recovering athlete. Unfortunately this item via Amazon was not as it should have been. The nozzles on the can are faulty and don’t work. It had to be refunded.

Very handy for my partner, she had problems getting her breath..but all sorted now..thank you..stephen

Excellent to help with my asthma and keep me out of trouble.

Easy to use, easy to attach to a mask
