Pocket Size Natural 3L Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance & Health (3 Pack)

Small, easy to carry around, light, easy to use, does the job, no taste. I got this for my Mom (who has some minor lung issues) to have when she travelled for a few days to altitude 7800ft. She used it a few times after climbing stairs or exertion to regain her O2 levels (we measured with a pulseoximeter). This product served us well.

Helps as advertised.

These were a lifesaver during my high altitude trip. I’m from sea level so it takes me a while to adjust to higher altitudes. I kept these small bottles in my jacket pockets, purse, ski pack, etc so that I had one at hand whenever I needed it. I used them for a full week and would not have done well without them. They provided that boost of oxygen when I needed them. No taste or flavor, just pure air. Easy to use. Will be a part of my packing list for ski trips going forward.

I usually got the 10 liter. This one hardly lasts at all. For the price, almost not worth it. However, works great for getting oxygen in your system.

Saw a commercial about it and decided to get for my friend as a stocking stuffer gift. Was well received. Said after working out, took a puff as directed and it worked very well. If continues to use, will purchase larger size. This smaller size was great for a stocking stuffer and to try out before getting the larger can, and also good to take on a run or outdoor workout.

I ordered this to see if it would help with cluster headaches. It does. The small size is perfect for my tote or purse. It has helped the puffiness, fatigue, and pain that comes with this type of headache. I ordered more and will keep using it. *I am not a Healthcare professional. It was my personal decision to try this product.

The value isn’t really there. It advertises something like 60 1 second bursts (so 1 minute of use total). In reality it lasted 10 seconds. It is small and easily portable but since it runs out so quickly you’re basically stuck with trash almost immediately.

I should have read the size of the bottles before purchase. This is the second time I purchased this product and the first time I remember the bottles much larger. I use these oxygen bottles to help me with my green headaches and they are efficient and relieving the pain in my frontal lobe. I'll just order the bigger bottles the next time.
