I bought this for our pre-teen grandsons to use hiking in the north GA trails. I set it before they go then turn it off to save the batteries. When and if they need it to get home, they turn it on and follow the arrow. Easy, reliable, safety device. It seems rugged, too.
Pros: easy to use
Cons: none
