I purchased this in Dec 2016. Never had to push the “SOS”. I pushed the “test” button once or twice to confirm it was working. And it was!
I take pride in how I care for my gear and doubly so with something this important. I handled, carried, and treated this like it was a new born baby. The handful of times I took it on trips, I carried it inside my sleeping bag or in another padded area for protection.
I will make sure it is unregistered prior to shipping.
Will ship in a well padded package.
$170 shipped any where in the Lower 48
