SIZE:
I bought small instead of medium considering all the reviews that it runs large. The fit is weird, if a had bought medium I wouldn't be able to wear it. Small fits not perfect.
It are warm (not super warm) and good quality, but buying without trying is not recommended, maybe it was my mistake to buy gloves online, is a type of product different from clothes that it can be a little bigger/smaller than usual.

TOUCH SCREEN: is ok, it works considering the problem with the lenght of the fingers, not the best but it works if you need little phone use (calling/answering mainly)...if you are buying to use your phone lot of time I don't recommend it.

QUALITY: seems to be good, have worn only one week in temperatures around 8-15 C (46-59 F), in lower temperatures I recommend warmer gloves.
