@fdixon63 Oops! My mistake - I corrected it on my original post - the one I love is the Muscle Hook. Here is one example, on YouTube: https://www.youtube.com/watch?v=fP4cBZDVYDk. I'm sure there are others

I use it as an acupressure device, not a moving massager like the film shows - to target the sore spots directly. It is great pressed against a sore spot as you gently stretch it - works wonderfully on my neck especially. I have noticed my husband using it often too. The other night I used it to gently apply pressure to some sore spots on the bottoms of my feet (brought on by working on the ceramic tile basement floor for hours - barefoot!) and slept without pain.

The reasons I like this over the others I have tried are the stiffness of the cane - easy to apply pressure without using a lot of hand/arm strength, the multiple knobs for different spots, and the extra "bump" & knobs on the center for (carefully) applying pressure directly on or next to the knots that form along my spine.
I brought it to my PT wizard & he liked it too - felt it was definitely an improvement over the original devices they have been using & recommending.
