Help please, I'm looking for the name of a massage product similar to
the backnobber.

The Backnobber is basically an "S" shaped bar with hard knobs at the
ends to apply pressure on hard-to-reach tense spots like in between
the shoulder blades. The product that I'm looking for is the same "S"
shape but the tips are made of rubber instead of wood or plastic. But
the thing is, I don't know this product's name, so all my internet
searches have been futile. The last time I saw this product was
probably about 5 years ago in a Relax The Back retail store.  I
already know about the Theracane, but am really more interested in the
"S" shaped device with rubber knobs.  Thank you in advance!

These devices might be of interest:

When my back gets itchy, I find that an extra round toilet bowl brush
works well to scratch and massage it.
There is a back product out there, which you may have to obtain from a
place that sells discontinued stock. It is called the Waterpik
AccuReach. It comes with two different tips that I think are plastic.

"Waterpik AccuReach"
