The Valentine pretty much gets the best ratings in every test out there. There are a few where it is rated second I believe, to the Passport 8500. I don't have the Valentine 1 yet, but I know people who do, and the fact that it shows you the location and number of separate radar readings is pretty indispensable. Say you are going by a shopping mall near your house, and you know it always sets off your radar detector. Well the Valentine 1 would show you the direction and number of signals it is getting. If you always are getting 1 signal by the mall, and one day it shows 2, you know there is probably a cop around. I have however been thinking recently of getting the Passport 8500 and the ZR3 laser shifter because the state cops in NJ are in the process of switching to radar, and that is probably the best protection you can get, but that goes for $800.
