Input:
I bought this as a Christmas present for my father-in-law. He is a retired cop but still spends a lot of time driving to see family. This unit is compact and very easy to set up and use. The weather stations come in very clear just about everywhere he goes. The only draw-back is the limited range. He is thinking about getting an antenna for his car to boost the signal strength. Overall, it's still a great product and a good value.
