If anyone is on the fence thinking about installing a Smart Siren II w/ pager, I can tell you first hand to go for it. Easy to install (09 FXDL) and it is a Trick System. Loud Siren & the belt pager has a light that tells you if your out of radio range with your bike. Nice Feature. Has warning alert (tamper) prior to full blast alarm. I have not tested the true range of the pager yet, but it looks like a Great Value for the price. Finally "some" peace of mind!
