I've used Passports...but now I have a Valentine One if that tells you anything. After my last ticket with the Passport, I had it... and gave it away to a friend. The V1 is upgradable when they change features, tracks multiple signals, tells which direction they are coming from, and it is by far the best money spent in my opinion on any radar detector system on the market. Lots of options for wiring, mounting, and accessories, plus you can integrate it into a laser shield system should you choose to do that upgrade. (I haven't since my quoted price was in excess of $2000)
