Yeah baby... I've tried others, but this one does the trick.
I previously used a callous grinder that looked like a rotating drum and it took forever to work down the callouses, not to mention being a drum, you couldn't work on a single spot. I was waiting to find the bench grinder of callous machines, and this is the one. Be careful though as it takes the dead skin off quickly. Use a light touch and you will be fine.
