Oxygen Plus – O+ Biggi 6-Pack | 99.5% Pure Canned Oxygen | Energy, Endurance and Recovery | High Purity Oxygen | 50+ Uses Per 11 Liter Canister with Mask

You don’t get very much in a can, it’s really hit and miss how much, but some only last about 20 breaths at max. I pretty sure it’s just compressed air. Very expensive and not great quality - will not buy again. I would not recommend people waste their money.

It arrived too late for me to use. They told me to keep it and they also returned my money. Works well.

Very disappointed. COPD using this type oxygen strenuous activity, sports etc. , Not as advertised, no air, complete waste money. Definitely canisters are not being filled properly . Truly unhappy with customer service, Done with writing back and forth without any type solution. Not used to this type of service from any reputable company. Would never purchase anything from them again. Going back to dependable U.S. company we’ve dealt with past few years. As a senior can’t afford to be loosing this type of money, no incentive to try new product - lesson learned- stick with well known company that stand behind their product

It does raise your O2 level but i maybe got 50 out of 1 can. Disappointed for the price i paid.

I received empty cans. Absolutely nothing in them.

Overall I like this product. It does well at delivering a bit of O2. Out of 18 cans(yes, I do like it) a couple of cans arrived empty. I didn't bother at the first event..but the second one caused me to contact the seller via their website. I told the my mini-tail of woe and asked if they would respond...Moving on and promptly forgetting about the event, was presently surprised with the quick arrival of fresh cans time two my described loss!..That's pretty fancy super-nice by any measure! WOW, indeed. So, good product, Really swell customer service, and a happy customer for sure!
