These gloves are nice and warm. The fingers are a little long for my hands, but not enough for me to complain about it. I mostly wear medium size gloves. The gloves themselves are a little longer than I would have like  (despite being S/M), though this would not be a problem during New England winters as such length would, for sure, provide a needed extra layer of insulation. I have tested these gloves in the iPhone 4 and these gloves are indeed compatible with it. However only the fingertips that are gray can actually be used to  operate  the iPhone.  On the second thought.. it is not as if this is a full keyboard on which you would use a complete set of 10 fingers.
I was not able to verify that these were indeed made in China. The bar code these came with started with 020, which makes me think at least some part of the manufacturing process took place in US (but I could of course be wrong about that).
