Query: a big help for aching hands

Obviously, there are a lot of uses for an immersion blender, but I got it to aid me in one particular task that has been nearly impossible with arthritic hands and a potato masher -- smashing beans for burrito filling! Beans do not mash easily with a potato masher (they slide out from under mostly), and that was very hard on my arthritic hands and wrists. The blender did a bang-up job on the beans, which couldn't get away from it as I moved it around, and up and down in a large, flat pan. I could've gotten the mixture even smoother if I'd wanted, and all in just two or three minutes. It was a bit noisy, but the vibration actually felt good to my hands, and clean up was a cinch. I look forward to using it on many other things that would be a trial to do by hand or any other method.
