I've had a pair for two years and wore them lots without plugging in because they are pretty warm without the heating.
The element in the left glove has just given up so i have purchased a new pair. you cant beat heated gloves in really cold weather. they are fully waterproof too. New ones are a bit clumsey, make sure you get the right size.
I bought the variable temperature control and drilled it to the bike - rain got in and flattened bike battery - a rael pain, so i;ve dumped the unit and just plug in when i need them.
i agree with chris, they do not seem to be a robust glove but good enough for me.
