Title: Durable but heavy
Review: Recently purchased these glasses in the 20oz size, and while they are everything they should be, they are very heavy, and the outside diameter makes them difficult to hold. The glass surface is very slick and can get slippery also, so beware. These are not for people with weak wrists or short fingers. The 20oz size is good if you want to sit yourself down somewhere and not have to refill your glass very often, but it's pretty awkwardly bulky if you plan to walk around holding a glass. I ended up purchasing another set in the 16oz size, and they are just enough smaller to be more portable, while still holding plenty of liquid for average use.
