Honestly, how far of a range are you getting? I've had mine for like five years, and it probably hasn't alerted me of a cop that's more than a quarter of a mile away. Which don't get me wrong, it is enough time to slow down. However, I keep reading people are getting alerts from up to 2 miles away? Why is this? Does putting it in a different mode give you a further heads up? I keep it in big L because it has too many false alerts otherwise.
