### ⭐⭐⭐⭐⭐ Mountain air!
*by C***L on April 4, 2024*

Needed a second O2 regulator to leave at the cabin. Mountain air is thin so this was perfect!

### ⭐ Quality of materials is suspect ... ya get what ya pay for!
*by J***R on May 18, 2025*

I thought I'd at last found a regulator that would do 25 lpm for a price I could afford ... and it did work for awhile ... but it only lasted 6 weeks. Two weeks after the return date some inner seal failed completely, allowing a strong flow of oxygen to flow out at all settings, even 0. So ... cheap junk, imo, save your time and money and look elsewhere. Also the meter showing the level of oxygen was a couple of ticks off, I ran out of O2 when the gauge still showed half way up in the red zone. Cluster heads can avoid this one!
