We have the Pro 7's, I believe. Haven't used them now for a couple of years. Had a TON of trouble with the interconnect cords. Sent the entire system back numerous times for repair, always with same "no problem found". Finally I found a problem in one cord that I could duplicate while using it. Drove us crazy- it would allow one of us to talk to the other, but not back the other way. Very frustrating! Once fixed, the system works very well. You can hear everything. The vox works quite well, though it clips about the first quarter syllabyl. I've got the bike power adapter, so the only thing that needs batteries is the radios we use. I even have outputs for a CD player. I'm just not impressed with the customer service. If you're interested, I'd sell my system, since we've got CB's on the bikes, we don't need this one. I think you could get it all under a seat, but it may be easier to pocket the pieces and just have one power connection.
