Vibrating Alarm Clock

Does anyone know of a vibrating alarm clock that you can adjust the level of vibration? I hesitate buying one for that reason. I hear it feels like an earthquake. No, thanks...not interested. Right now, I use my phone, which is good enough for me, but it needs to be close enough for me to feel the alarm go off. It would be nice if it could be used for travel. I don't find this specific feature that you can adjust the level of vibration. I used the flashing light before, which was okay for some time, but I find I prefer my phone set to vibrate. It's low enough but effective in waking me up.
I don't see myself using a watch all the time. I wanted more like a small clock that you can have a lower vibration strength rather than a standard strength level as every one is different.
