I got my H1 and I've been using it while out hunting. I've noticed a few problems and inconveniences with it. I was reading the other questions on this forum and it seems like the software is a bit unfinished so I'm hoping they can still fix these!
1. I get in and out of my truck alot while hunting and when I plug it into the trucks USB chargers the H1 goes into I guess USB mode? It shows the USB symbol on the screen and can't do anything else. It doesn't do this when I plug it into a phone charger at my house. Crazy that you can't use the device while charging
2. I set the action button to mark waypoint with single tap, start flashlight with double tap. I can't reliably get the double tap to register. I double tap and it does the single tap action. I've tried pressing it more quickly but it is extremely hard to make the double tap work
3. You can't change the color of tracks on the map I think others have posted the same thing, so this wasn't surprising
4. The compass gets really laggy when you're moving. When standing still its really quick to react to orientation changes but as soon as you start moving it seems to stop working, and when it does work it updates really slow.
