I have been using a Valentine1 for about 5 years in my truck and on my bike. So far no tickets, been close but no cigar for the man. On the bike I use the Marc Parnes LED's for a signal. I got tired of the audio sound in my helmet. I'd rather listen to music than chirping to door alarms in conjested areas. So far the LED's are working as advertised. Very bright at night almost too bright. Just right in the daytime even with a summer sun at your back. I did have one problem early on with my Valentine. It stopped working on K band which nearly cost me a ticket. I contacted Valentine and sent the unit back. Week later it came back good as new at no charge to me. I need to run the serial number and check the updateness of the unit I just have not gotten around to it. Instant on radar is hard to detect but you learn to be just as sneaky as the man on how to use or not to use your radar. It just takes practice. I don't do 100 mph down the road everywhere (well close

) but its nice to have because most of your speed trap cops are the one horse johnny types not the state troopers. The one horse types tend to cruise with it on all the time the troopers are a little more sneaky with it so you have to pay attention to what your doing out on the highway. I usually let a faster vehicle run 1/4 to 1/2 mile ahead and just let that be my instant on warning

when they get pinged I know it instantly.
