Remote controls with dying batteries are so annoying. You never have batteries on hand when they die (what else uses AAA batteries these days?), so you end up walking up and changing the channel by hand until you face your laziness and go out and buy some. And the cycle continues.
Not so with the Wind Up Remote. Rather than batteries, it has a little crank at the bottom. 30 turns of the crank and you've got enough juice to last you for a full week of regular use. You'll never need to buy batteries for it again. It's good for the environment, good for your wallet, and good for your sanity. What's not to love?
