Garmin has been great to me and my huntin buddies when it comes to customer service..
Same here, no BS. Great repair and warranty service. I have two Astro units, around 12 collars. I just had one of my Astros shut off on me last hunt, the blank screen thing, with good batteries. I had to hit the power switch and turn it back on. Did not lose any data. I was hunting around 3 others with Garmins, so who knows the issues.
