Is the valentine really that good? I mean it would be my first radar detector so i have no clue how to use it to its fullest. I know that it shows you an arrow of where the zapper is coming from but like is it a jammer too? Afocoryw20, the valentine is a radar detector, here is the website,
www.valentine1.com . So the 19's will be ok? would my local bmw dealer put the wheels and tires on and balance and allign them for me?
