Not surprised at all unfortunately. I don't know about their repair policy, but in terms of features, everybody I know who ever tried a Coros watch never went back to anything else. I tested a few, they're pretty cool indeed. They're usually quite expensive too though. Myself, I've been in the Samsung ecosystem for so long now that I will probably not change, especially with their excellent trade-in offers for upgrade. But if you don't need LTE, it's probably not the best fitness choice (leaving my phone at home or in the car during runs or bike rides is a given, and in the past I still needed to be reachable, hence the LTE need)
