Valentine one once offered a 1 year trial and a gift of $100.00 if you returned your V1. Nobody returned the V1. It's that good
(mem-tek that was a joke)

p.s. On a serious note I think you should try for 30 days. Some people hate the false alarms. I for one would never use a V1 unless I had the smart cord to mute it in the city.
