1. Non-standard 23mm strap, which has no alternative. I did not think that this would be a problem, but you simply will not find another strap on them. Native silicone is uncomfortable, and metal costs like a locomotive. 2. Compass. Too sensitive to tilt angle. It turns out the accuracy of the readings plus minus 15 degrees. It won't even get you out of the woods.
