We had bought us this device actually for our two year old twins with bronchitis problems and resultant frequent shortness of breath. Unfortunately, the device does not provide reliable values for the corresponding small fingers. For us adults, but it works perfectly. We can say this because we have matched it with professional equipment in the hospital. The application is quite simple and intuitive. Finger pure Knöpfchen pressed, already there are the values. However, the device was probably designed for Nursing, if you want to read the values of others. If we make it to himself, then the values are upside down. These coarse digital numbers not very easy to read and rather impractical. In practice, however, on the one hand, the waterproof protective cover that is included. On the other hand the shoulder bag with Velcro and a long cord. Great accessories.
