So far battery life seems solid, probably one of the best for heated gloves I've had, but comes with the tradeoff that its an awkwardly shaped battery that does protrude more than other make/models i've tried.
They are comfortable, though I feel like they could go a bit warmer on max setting - but I'll give a bit of a pass there because my hands are always cold.
My biggest gripe about these though is they really need some kind of wrist closure - They aren't really small enough to fit under another glove like a liner, which would otherwise explain the lack of a wrist closure. They kind of 'float around' a bit more than would be ideal because of this so the fit could be better.
If FNDN fixed this wrist issue and made the battery a bit thinner and flatter instead of tubular these gloves would be a 5/5.
