I'v been using one for about two years now and it works great. Only had one problem; It woke me up one morning with the sound of a baby crieing???? The wife and I looked at each other with the "what the ******* look" Turns out a couple with a baby just moved in next door and we were on the same channel. Those things have some range, that house has to be 100 yards away. Went to channel B and all's well again. I thought about switching to their channel around 5 am and firing up the chain saw!!!!
