Excellent
This callus remover is excellent. I had the other chargeable kind with the snap-on head previously and there’s no comparison. The chargeable had little power/ran out of juice on a full charge before finishing one foot and was super noisy. This one is powerful, quiet, love the variable speeds, and while it gets warm to hold after using for a while, did not overheat or die out after using it for an hour straight. It keeps going at the layers, too, while the chargeable one only went so far. I recommend getting replacement sandpaper discs with 80 and 180 grits so you can do some smoothing after callous removing (or use a fine grit pumice stone afterward).
