Head Massagers? What is the view on getting one?

Seeing how beneficial massages are, an the only thing getting in the way is keeping up with doing them, how about buying a head massager? Obviously if we had an effecctive one, we could put it on our heads and leave it for ours, without having to tired our fingers for hours.

If so, what devices are there on the market? I have come across a few that talk about massaging the acupressure points on the head. I've think they work with blowing air. Lol, is air sufficient for this?

I'd say stick with cd's pill bottle method for massive hand strength gains
