I dislike writing reviews but in this case feel I must! I decided to buy these walkie talkies (in fact mine are the Action 950's) on the basis of the earlier reviews, and to my surprise found them entirely justified. These units are certainly not toys, have many features usually associated with professional equipment yet are easy to operate. I must admit that I was very sceptical about the claim of a 10km (6 mile) range yet I found this to be quite true on holiday this summer when I was able to communicate the full length of Loch Broom, Ross-shire. OK, so this was an open-water/line of sight situation but nevertheless this performance was outstanding. For non-line of sight comms don't expect anything like this range and you will not be disappointed. Excellent product, fantastic value.
