My hands have been really cold so far this year so I started looking at heated gloves. Most of the heated gloves are very expensive, and most got poor reviews, specifically that the heat was concentrated on the back of hands and none out to the fingers.
Then I saw these liners which indicated continuous heating to all fingers. Since I already had several decent pairs of gloves I figure heated liners might be a better choice.
I'm ordering a pair of these heated glove liners from Costco Canada, but they are a Christmas present so I won't be able to review them until the end of the month. I was planning to buy them even at the full $179 price, but they launched today for $36 less for the next 2 weeks.

Instead of using a wired resistor creating a point of heat, they use bundled carbon fibers as the heating element. It turns out you can buy carbon fiber heating tape / rope to make your own heated stuff. There are a bunch of diy tutorials here by a guy who sells the flexible heating tape.
So if might be possible to cobble something together quite a bit cheaper.
