I'm always looking for new and interesting ways to make myself get up in the mornings. Big fan of Clocky and it's ilk, so I thought I'd give this a try. After the first morning, it appears to work as advertised except for two big problems and 1 minor one:
1. The alarm sound doesn't go off.
2. You don't have to aim very well to hit the target. Heck, a full 15 degree arm swing right of the target was enough to check it.
3. You can record your own sound, but even on playback, the sound is extremely soft. Since it doesn't play at all when the alarm goes off, it's kinda academic though.
Do not waste your money folks. Try something else.
