Large Breathe Menthol-Eucalyptus Aroma 10L Canister | Respiratory Support for Aerobic Recovery, Altitude, Performance & Health (2 Pack)

Great product. I purchase this product when traveling the mountain regions in the SW. Helps greatly, especially when we are at elevations 6000 ft or higher. This oxygen is highly recommended to have on hand. Helps kids as well. If you live in low elevations and go to the mountains, get this product to avoid dangerous altitude sickness.

As a Naval Veteran family that lives on a fixed income your price and Excellent shipping time will keep me buying

I bought this for my Dad when he needed oxygen part time at home. It gave him something to take with him in case he needed an oxygen boost. It made him feel much better!

First learned of this when visiting my kids in Denver - the mile-high city. It's common there for acclimating to the altitude, and to enhance exercise. Used it while there, and then ordered it to my home after that visit -- I now use it before exercise for better sessions. It works great, and my GP said it is fine (although I will also get confirmation from my cardiologist at my next apt). The only thing I don't like is not being able to tell when a can is empty. This has already messed me up as you can tell ZERO difference between a full can and an empty one... no weight difference at all, and the "numbers" on the can don't seem to give you any hints. Be sure to mark/date cans w a Sharpie, I ended up wasting 2 cans because I wasn't sure which was empty - seriously, it's impossible to tell!

Good to have as a standby 02 system. I have used it often.

These are great! I have ordered more

Been buying this for my father in law who has copd, it helps boost his breathing everytime he stand up or go to the bathroom. He is been catching his breath and this kinda helps him somehow. Am giving 3 stars only coz its too expensive for just 3 pcs

Great product too expensive .
