I am very satisfied with the inforad K 1: inexpensive, almost perfect: 2,700 km, Paris-Marrakech, I saw only two mobile cameras for which I had not been warned! One downside: the plastic bracket with sticker is not solid. Mine broke the medium after 3 days! I thought to ask for a replacement, and then I decided to replace it with a small square of velcro which I stuck half on my dashboard and the other on inforad. Impeccable.
