Review on DECVO Powered Thicken Fingerless Cold Proof by David Underberg

So it only gets hot in one place: the removable pad that sticks to the palms. For me personally, this is the least useful place, so I put them on backwards to warm my palms. They only work when plugged into the mains and the cable that comes with it is quite short. That's fine for a laptop, but if you need them for an office where your computer is behind a monitor or under a desk, you're out of luck without an extension cord.
