I've literally had my butt saved by my Garmin inRreach Mini 2. And I've thoroughly tested its strength against pretty much everything its engineers would've never even thought of testing for, including leaving it in a river for half an hour, running it over with an ATV, a UTV, and my truck, and bashing it along every rock face I've ever fallen on after taking a tumble on a plethora of motorcycles.
It even survived the fall off Royal Enfield's Himalayan 450 and into a deep mud puddle during the most fun, gnarly launch I've ever encountered. And that's after two years of constant abuse and a lack of mechanical sympathy that I can only describe as vindictive.
And I've tested the Zoleo, as well as the Spot IM satellite communicators to similar extents, with the Zoleo being subjected to my exact same original test as the Garmin. The only reason I've put my inReach Mini 2 through more, however, is because I think the user interface and functionality are better than the Zoleo. But its function of being able to take a hit and keep on ticking until you need to press the SOS button, that's just as good as the Garmin, in my opinion.
