I got a sena. I used it on a few long trips with my wife but even then you don't use it much. It did help me find my phone when it dropped outta my pocket and the "pairing was lost"
personal opinion, pretty useless.
that said we went out rippin offroad last weekend, woulda been nice, assuming a good enough range, to have a better answer to "where's chris" than all going back down the random trails to see where he ws broken down
