Four of us went skiing last week in Andorra and took these little beauties along. They saved us a fortune in mobile phone bills. Really excellent, although I haven't much experience with walkies to give a comparative review.
Here are some plus points - really small and ruggadised (rubber on the outside), handsfree headset socket, headset included, chargers included which are really small for travelling, EU power adapter included, voice activation, ring feature (so useful when skiing and unit is inside a big coat pocket), great range.
To be honest, I'm not sure the range is 10 km as advertised but we were able to use them to meet up when some of us were at the bottom of the mountain and others at the top so it's plenty for skiing. I'd thoroughly recommend them.
