I used to work on film sets, particularly when you are iether in a large indoor set or evenon large location shoots, you can´t beat these things, their long distance range is phenominal, we would often send out a PA to pick up some KFC in the nearest village about 5km away, and he would radio back confirming everyone´s order!! Great fun, and an awesome tool... So to answer the first posters question, yes, it is a piece of great kit and a worthwhile review if you actually are someone who gets off the couch and puts down the remote / laptop from time to time!
