Does the trick
There are a few versions of this type of back massager out there. Some have a lot of knobs sticking off the body for various use cases... this one just has the two knobs. I'd say make sure you know what you're going to use it for before deciding on which one you want to buy. This one works good for me and I like how it's simple and doesn't have the extra knobs which might get in the way. I like it.  I would recommend it if you're looking for something like this to relieve soar areas in hard to get to places.
