I have used this device for some months now, and also highly recommend it, but with some minor caveats. I take it on travel and use it for long distance calls from hotels, etc that provide wideband internet. Note that the device does NOT work without wideband (no dialup). Also don't try to use it over satellite internet -- the inherent delays are not acceptable. One other item is that it does not work well with speaker phones. You can hear the other party well, but your outgoing can be noisy, etc.

If you need to make calls from the US/Canada to overseas, there is an additional cost (relatively low) but you must establish an account. However, it appears that making calls FROM overseas to the US/Canada comes under the unlimited/free setup !!

With those comments, its easily worth the price.
