To get to the point these gloves work!  Make sure you get the right size glove because your fingers have to make good contact with the inner surface of the glove for them to work.  If there is space at your fingertip then you have the wrong size, not the gloves fault.  I can use my iphone and type on the screen.  Takes a while to get used to but works well.  Gloves are pretty warm but given they are thin you can't expect too much.
