this is great will buy again , used it after i felt tired and I felt it helped and perked me up ! Should be headed for a sleep study so this has more than one use , after a workout im sure its helpful as well .... great product ! easy to use.

Great for folks that have COPD when you overdue it a little.

I bought this for a trip to Colorado Pikes peak and let me tell you it was very helpful on breathing I would recommend yo get some and take with you for these higher elevations trips

Love the product but what bothers me is the difference in release pressure from can to can. Using it to get over lung radiation, great but...... Mike R

Love this product. Don’t be without it

Fast delivery and exactly what I ordered.

The last 2 orders have had empty canisters in them. I have never had any before that did that. Usually I can feel a blast of air. This may be my last order. Once could be an oversight or malfunction. Two orders messed up isn’t a malfunction. I have depended on this order for quick relief. No more. Plus the paper measuring tape has never arrived.

This product may be good for a blast for limited one time results. But in case of serious needs, such as bad air or medical needs, this is no comparison to an Oxygen Tank with a hose caring liters of oxygen into your nose. While these small portable canister have a purpose, consider the larger sizes.
