I'm a newbie so hopefully you can pardon my ignorance and the wide open nature of my question.
How long do you expect your V1 to remain an effective detector? More specifically:
1. How long does it take for them to wear out from normal use? I'm not talking about being abused but just from hours of use and number of uses.
2. How long do you think it will be before it becomes obsolete as far as the types of speed detection equipment that it can detect?
To narrow my question down a bit, this assumes that I buy the detector new now and don't update it.
