I've got a sudden urge to buy a set and either need some talking out of it if it's a crazy idea, or advice of which ones (not too £££) to go for if we do.
We're going camping week after next in la belle France and have romantic notions of using it between me and DH when one he is washing up and the other me obviously! is drinking wine back at the tent and I can call him on the walkie talkie to say romantic things like "make sure you scrub the pans well" and "watch out, I've sent all our kids to help you" :o
Also have ideas of the kids heading off with them (eldest is only 5 though) and being able to radio to us when they get scared by the campsite donkey 
Have any of you got them and do you swear by them, or am I just mental and should save my money for some much-needed umbrellas?
