My K40 works good, they give you a year warranty, and they pay speeding tickets for that year as well, I have owned mine since December of last year, and to this date I have yet to get a ticket, it has saved my ass many times, so I can see why they give you the garantee. I thought about a V1 but that was way to much to pay for a radar detector IMO. IIRC I paid around $240 shipped from sounddomain.com
