Brilliant compact device; easy to sue and see when it is on. Feels like fresh air when you breathe!!

I work outdoors a lot, and am a frontline worker; I want to be able to work freely without breathing problems, especially in the current pandemic.

This device is perfect, it is light and easy to wear. I also use it in the car, especially when i am travelling with the air conditioning.
