I wish I had done my research before buying the 30k... My wife and I do long-haul road trips with it, and the fact that it's not waterproof is a big deal for people who are going to be forced to do some driving in the rain. Now, I can see corrosion on the contacts and experience frequent drop outs and distortion from poor connections (it improves if I wiggle the device the right way). The Cardo communications system would've been much more practical for us. Somebody must've already suggested this, but I figure there's power in numbers.
