The smaller bottom side also makes it easy for my small hands to grasp it
My son purchased this for me for Mother's Day.  My first thought was that while I appreciated his thoughtfulness I didn't think I needed another travel cup.  After using this cup I have thrown all of the other travel cups away.  This cup keeps my beverages cold and the ice doesn't melt even when I leave the cup in the car during the day or on my night stand at night. The cup does not sweat leaving water on my night stand or in my car's cup holder.  It fits in the cup holder and no matter how aggressively I make turns, this cup does not fly out of the cup holder and end up on the floor of the passenger's side.  The smaller bottom half also makes it easy for my small hands to grasp it.  When I get a migraine, the metal straw delivers really cold water to the roof of my mouth better than a plastic or paper straw and it's better for the environment.  The straw can be easily cleaned with a pipe cleaner if necessary.  Best cup you will ever purchase.
