I have used one (V.2) for about 3.5 years with near perfect results; failures to transmit are perhaps 5%, although a few weeks ago I experienced two failures in a row testing from downtown SF; later tests were all 100% successful. I've used mine in Washington State, Sierra Nevada, and South America. In this regard: would recommend strongly.
See another recent thread for the parent company's shitty tactics in erasing complaints and ignoring customers though; that's a different bag altogether, and if i were purchasing one today, i would very likely consider a different product/company; being treated shabbily shouldn't be rewarded with more new business, so bottom line: NO
(are you listening, General Motors/Motorola/HP/Dell/BankofAmerica - ? etc etc)
