I've got the Chatterbox FRS X2, as does a buddy I usually ride with (he has the add on passenger set-up for his g/f also).
If it's just you and the wife, on one bike, I'd suggest something cheaper. There are other wired intercoms that'll work just as good and wont be nearly as much.
If the two of ya are on seperate bikes, they're not bad. But watch out with the helmet mount. Both mine & my buds developed a crack. There are replacement parts available for about $5, but I ended up mounting mine to the handlebars, and then made an aluminum piece for my buds cause he'd rather have it mounted on the helmet (easier that way when used as just an intercom).
The headsets work pretty good, but wind noise can be an issue if using the voice activated method at speeds above 50. With openface helmets, it'd probably be a bit less.
The range isn't too bad. On straight roads you can get close to the two mile range, but when hills/buildings/alot of turns get inbetween, range can easily be cut to less than a mile.
Battery time has easily lasted a good days ride, but I also got the power/charge cord just incase.
I don't remember where I got mine, but I searched online for the best price I could find and got both sets for alot cheaper than what something like Dennis Kirk has them for.
my handlebar set-up.
The aluminum piece that the Chatterbox is attached to is the piece that seems to crack kinda easily.
