I haven't used it personally, but all reports that I've heard about it are positive. very nice 1/4 mile or so range, and goes through walls well. However, don't downgrade to either of Eartec's lower price wireless com systems (the 900mHz or the 2.4gHz one), because I've yet to hear a good thing about them.

However, as with almost all of the main wireless com systems, you can only operate 4 beltpacks at once.
