I have been using escort products for years and I have an urge to buy a new gadget and I am thinking of buying a V1. I have been reading this forum for a few weeks and one thing I keep seeing over and over again is that people are sending their V1's in to get tuned because they may not be working correctly. Before I spend the money they are asking I am curious to know that when you turn on a V1 does it do a Self Test or Self Calibration to let you know if the detector is working correctly? The Escort I am using now does and besides that I never in the past had to ever send any of my units in to get fine tuned. That is something that would make me not purchase a V1. I don't want to have to guess if it is working correctly and if it isn't then I would have to send it in. Anybody who owns a V1 please respond. Thank you all for your time and for responding.
