My wife and I are going to Panama City over the holidays - on the bike - and we thought it'd be a good investment if we could chat along the way.

The box is flashy, promising a "5-minute installation". The other "bait" to get you on the hook is the wireless "Bluetooth technology". So far so good. I paid US$ 288.oo here in Costa Rica, since getting it in time from Amazon would have been a problem.

First impression:
The system did NOT install in 5 minutes. A construction flaw in the provided helmet-clamp made it necessary to switch over to the glue-clamp method, which expressly says: "Wait 24 hours before installing the rest!"

First test ride:
The system is hard to activate via the VOX command. One has to literally YELL at it so the mike/voice channel will open up. After that, even a short lapse in the speech will make it to turn off, resp. go into standby (the manual says that it will stay ON for at least 25 seconds).
Intelligibility is fair, but good enough for voice. We'll get used to it.
The speech has always a slight background "sizzle", which is probably due to the bluetooth technology.

Connecting a MP3-player:
Simple, via provided cable, but the sound is catastrophic! Less than tinny, like listening to the guy next to you on the bus who has his earphones turned up too loud. It is "stereo", but that's about it. Even turning up the volume of the MP3 to "full" did not improve either loudness nor quality. (I am an instructor for sound and acoustics at a local university, so I know what good sound is, and what is really bad).

Bluetooth phone:
Works with my Motorola RAZR V3, but here again: the sound is less than acceptable. Too low and too tinny!

Will comment more once we get back from Panama...
