My Verizon Razr speakerphone works great half of the time and is a disaster the rest. People I call and I both experience every second word cutting out; or there is an echo - people I call say it sounds horrible, they can hear themselves and it is not pleasant. This is the second V3c in 10 days; the 15-day limit is coming up. When I called Verizon, their folks heard the problem twice; they're offering a third sample of the phone - but is it worth it? BTW, speakerphones on previous (LG) phones weren't great, but none of this.
