Purchased a pair of these: http://cozywinters.com/shop/heated-glove-liners.html to replace the battery-powered ski gloves I've been using for about 5 years. Thought they might be superior to the battery-powered gloves when used in conjunction with ski gloves. Got to test them at cold WRL, today. My hands stayed warm on the lowest setting (the liners I purchased have 3 heat settings) and actually started sweating. No hint of the Raynaud's Syndrome I suffer from. In the afternoon, I switched unheated glove liners for the heated liners, and experienced Raynaud's Syndrome. Found the battery-powered glove liner/ski glove combination to be more effective in keeping my hands warm than my much more expensive battery-powered ski gloves. Purchased a spare LiPo battery pack for $99.

This is an older post - I assume all is well with the glove liners.  However, an up-date would be nice - as the years go by my fingers and toes kind of get cold and seem too stay that way most of the winter (being in Texas helps, but ...)  I have to admit I probably under dress for the cold, I can tolerate it better than the heat anyway - but the tigers are another story.  So I'll give these liners a shot

PS my Mom has Raynauds, maybe I m like her????

Jay, any idea how well their Thermo Soles work?  I'm tempted to give them a shot.  

I bought 'glove liners" extra batteries also.
 
I gave them away.
