It's a "Car & Home Neck & Back Massager Pillow". It's a mouthful but that's the official name, lol. I'm not using it for home - I already have a much more sophisticated one for that. The one I already have also has an inbuilt battery, making it actually portable.

I once sat in a friend's car that had massage function in the seat. It was an interesting experience - very relaxing, especially with the warmth in winter. While this gadget doesn't turn your car seat into a proper massage chair, it at leasts allows you to get a little taste haha.

This is a quick demo of the product. In the video I actually didn't put the strap in the correct place. It's supposed to sit a little lower so it hits the lower neck.

I actually received two different versions, as shown above - you can see the other one is black with more buttons, so I've picked the simpler one and given the other one away. I don't think I'll ever drive with it working, or that it's legal to do so anyway, because it could be distracting. Heavens forbid, one could fall asleep while driving due to over-relaxation haha.
 

Peace & Love,
