Very good machine, I used it continuously for 2 years, suitable for children from infants up to 8 years old. It has 2 masks, a smaller one and a larger one. If you use it regularly, remember to change the small air filter.

I don't know how long my model will last, although the reliability of Omron is guaranteed.
It does everything I expected.
I would like to emphasize that I was familiar with the model before purchasing it, as our pediatrician had lent it to us in the past for use.
It doesn't need to be unnecessary.....
