I have assigned a rating of 4/5 because the product matches my expectations. I hesitated to choose a weather station, which I found quite functional, clear and with rather positive opinion was it, more than it has the distinction of having a dual power supply. I appreciated the clarity of the information, the backlight, small alert messages, the frost alarm if the temperature is below 3 ° C. It is initialized only with the clock and the external sensor; it takes some time to adapt. She mentioned the indoor temperature well as external to a few tenths of a degree.
Also, be aware that the station works with 3 batteries and the solar panel is used to conserve battery batteries. Not knowing the life of this small panel, we remain skeptical. I must admit that despite the small problem, this device meets my expectations, I am not disappointed. Would recommend to anyone who wishes to have a clear information of a simple nature of the weather conditions.
