How about if I create a battery powered hand warmer to place inside my gloves, battery included...
...
Have I earned your 10$?
LOL, nice try but I should have been clear that I mean
existing products.

Most people here could easily design and build an item which would take advantage of the Batteroo Sleeve's silly characteristics and show a net gain.
These do not count! It has to be something that was not intentionally designed to "game the system."

P.S. Even though your hands might be warmer for the time it DID operate with a Batteriser, because the energy was being extracted more quickly from the cell(s) it would probably provide less total heat with the Batteriser than without, humorously enough... That could make for an interesting test for anyone with a good calorimeter.

I'm beginning to wonder why they even bothered to design and put any circuit in the device at all, they would have made more profit with just a mechanical battery holder...
That is why this whole saga has been so thoroughly entertaining... Nobody is quite sure whether these PHD engineer "GENIUSES" are really as clueless as they appear or if it is all an elaborate, intentional ploy to slurp money out of unsuspecting masses with their vague, evasive marketing wankery.
Why did they never publish any data if they are so SMRT and their product is so great? This whole thing makes no sense, which is why we've all been watching!

I've seen the 'wireless' anti-static wrist band which Dave debunked awhile back...
There was nothing there to debunk.

That one is simply a language-barrier mistranslation. The manufacturer / packager meant "sans cord", meaning it is the wrist strap part only. Cord not included. They didn't mean it magically works "wirelessly". They're not stupid.

There are plenty of times where you want to buy extra wrist straps
or by just buy extra cords (or make ones, or have devices or stations that already exist with a hookup for your strap) so you can have each person around a facility have a wrist strap on, then just plug in when they get to that device, workbench, etc. etc.
They just meant
wrist strap only, not "wireless" in
our common usage of the word... This kind of wording error is very, very common and while it may occasionally cause some confusion, in cases like this it wasn't intended to deceive.
