I know I wouldn’t recommend one of those electric hand mixers, like the one that just has a tiny blade it spins fast (the ones that spin two “interlocking” things might do decently). The potatoes are too thick and the blades just end up pushing the potatoes away and spinning uselessly. I’d take the one pictured over that kind.

And tbh, I like that style because you can still get good smooth mashed potatoes and the masher is easier to clean vs the grid style ones. Though for either of them, the trick is to dip it into the dish water and shake it around (clear out fragile stuff first obviously).
