Boost Oxygen Medium Breathe Menthol-Eucalyptus Aroma 5L Canister | Respiratory Support for Altitude, Performance & Health (2 Pack)

Great product, wife loves it and easy to use, you don't need to carry oxygen around. If you just need a little help she only takes a few hits then she's fine, good stuff.

I have used this product for years & what's very excited to try new flavors. I first discovered this when I was in a mountain town where the elevation was over 11,000 ft. It really helped balance my oxygen at that time & I've used it ever since. I prefer the smaller size cans, because it 's easier to carry in my handbag.

Ive used this before, good product. My issue was with packaging. 4 loose cans in a big box. Not cool.

Lifelong asthmatic with early onset copd, ordered this for a boost at night when i have some troubles with oxygen. Works perfectly, as advertised. Great for the gym also for that workout boost. No Complaints

Used those before, did not feel much which might be a good thing. My teenager will participate in 4-day long swim competitions soon. She plans to use those in between the races. This particular pool is famous from bad ventilation, so she wants to try those oxygen "tanks" and see if she can avoid getting sick after the weekend as she always gets it in there. The price was competitive, portable size is great to keep it in backpack and it is totally legal. We choose no scent to avoid any headaches.

No taste, just pure oxygen. Also helped my breathing

I'm a very big & tall guy (6' 9" & 220 lbs), & have spent the better part of 25+ years exercising (both wt. lifting & aerobics), all the while struggling with lung & O2 issues I've had since birth; meaning that no matter how much cardio I do, I will still fall short of those without this condition. I've used O2 tanks (the heavy / hospital variety) & have been on steroidal inhalers to help increase my O2 when exercising, & each of these methods have proven quite effective in maintaining my endurance along-side those who don't have this condition. This said, the prospect of an ultralight O2 delivery method was quite appealing (even over the inhaler). Alas, it's all smoke & mirrors. For those who swear by this product, I'd also like to mention that in hundreds of thousands of case studies, where a placebo was used, the placebo would occasionally perform just as well as the controlled product; e.g. "mind over matter". In my case, since I have a REAL O2 delivery system (e.g. the med-ox regulator), I can compare how it works to this product. Even when using a foam seal (made from pipe insulator) to help "seal" the rim of this product around my mouth, I feel no different than when I breathe without it. By contrast, after running for 30m< &/or huffing & puffing during &/or after an intense cardio workout, both my "O2 tank" & inhaler offer me near-instant O2 relief (with the O2 tank offering my more "satisfactory relief", faster; hence why this product seemed more appealing than my inhaler). Add to this that when I check my pulse oximeter after an intense workout & use my tank or inhaler, my O2 levels out (to normal) pretty fast. My O2 didn't increase OR level out with this product, but rather decreased (I think b/c it is NOT "pure oxygen", & by putting it on my face, thus restricting my high-volume breathing, actually decreased my uptake). In short, if this works for ya... great. But for those looking for a REAL O2 boost, I'd say stick to O2-restrictive masks (e.g. build your endurance the long & steady, but true, way); adjust your diet to accommodate better red blood cell creation &/or O2 uptake; look up breathing exercises; consider a small, light-weight (1< lb, 25 LPM) O2 tank, to use during or after an intense workout as "recovery O2"; &/or talk to your doc about how to boost your blood O2 (especially if you have O2 medical conditions; like me). The take away..............................? It's a nice concept, but ridiculously fails, as it is NOT "95% pure O2", like the manufacturer claims. In a nutshell, you are spending $10+ for a nice-looking, brushed aluminum can... filled with the same level of O2 you can get by stepping outside. For all intents & purposes, you could take a large garbage bag & "capture" the outside air & breathe from that while working out to get the same effect as breathing from this can (for my own "control test", I actually tried this, lol; & both my pulse oximeter & O2 gas detector reflected this result as well ~ just as other reviewers have stated / shown w/ pics).

For home use the 10 size is better buy. Since certain celebrities got involved in the company the price has gone up considerably. If you need oxygen on a regular basis, buy a Concentrator machine. Boost is for limited home or sports use. 3 stars is because I feel the price is to high.
