What I specifically like about this is that you can set it to run for 1 to 3 hrs or just leave it on

You can have it set for 60, 120, 180 minutes or set it to the on setting which will run for several hours

The diffuser was as described and the shipping was very fast

Overall I am very happy with my purchase and would recommend this diffuser to others

We have it on all the time due to the fact that we all suffer from sinusitis and we find by have cool mist diffusers in our home that we’re able to breathe much better

It holds a half litre of water and will run for 10 hours and will shut itself off when all the water is gone
