I have an irrational objection to the little battery powered whisks that
seem to be all the rage for those whose coffee has to have foam on top -
they just seem like a bizarre waste of resources, and that in 1 months
time there'll be millions of them in landfill.

We use ours so much that we've got through 3 sets of batteries. It is
impossible make milkshake without them, unless you just like brown milk with
bits floating in it, or enjoy assembling, cleaning and packing away food
processors.
