Bests & Worsts Reviews from Amazon

These "glasses" are sturdy, large, and high quality. I've also washed them once on the top rack of the dishwasher just fine. Just be aware that because they don't taper as much as other brands, you will need more space to stack them (they go about 1/2 into each other) and they tend to stick together a bit more than others i've owned. You will need at least 10.5" of height to stack two glasses. I just happen to not have that much height in my cabinet. I'm not downgrading my review of them or anything, but it might be helpful for some of you that have limited storage as i have. Stackability never even entered my mind.
