This whiskey glass is very high quality, and it does prevent condensation.  My only complaint is that, by giving it a double wall, the circumference of the glass was expanded to the point where it’s too big around for me to comfortably pick it up with one hand.  I am a good-sized woman, I wear size 10 gloves, so I imagine most women would find it even more awkward.  I am going to give them to my brother.
