Title: Simple, Reliable, Long Range has a Down-Side
Review: This is a nice, reliable device. Battery lasted about a year with limited use. My only issue with it is that everyone in my group uses the same device, and we have yet to figure out if there's a way to change transmission frequencies. When we are in ajoining training rooms one of us has to stop using the remote otherwise we end up changing each other's slides. That's the down-side of having a longer range. But in general, we are very happy with it.
