I have one of these things, and I love it so much. The sound it makes keeps changing so you can't tune it out, and it flashing while moving around requires a bit more mental awareness to actually find the button to turn it off, so it's pretty good at waking you up.
For anyone else who has one: if you double click the third (alarm) button, you can change the default 1 minute snooze. You can also press the first two buttons at the same time to test the alarm going off without sound or the right two buttons to test with sound (albeit quieter than a real alarm).
Yeah, I remember seeing that one; I thought of buying it, but I'm sure it'll just trigger my "screw it, I'll stay asleep while half of the neighborhood secretly hates me for the morning noise" adaptation. I don't think I ever experienced a noise I couldn't sleep through.
If there is one, it would be this, it's loud and continuously cycles through so many different noises, there is no pattern you can tune out. I can't find a recording of the whole progression, but I can assure you it is very long. I should record a full video of it.
