Title: Hard to clean
Review: These cups are so tall and the aperture so narrow my hand won't fit more than half-way down so I can't reach the bottom to clean them. When I put hot beverage in it there is not much insulation. The outside of the glass gets very hot quickly and gets uncomfortable to hold. Also they are heavy and the grip is not very tight so there is a fear of dropping it if you don't set it down on a table while you are using it.
