QG Clear Acrylic Plastic 16 & 26 oz Water Cup Square Base Tumbler Set of 6

We've had these glasses for a few months now, and really like them. The plastic is crystal clear and have gone through the dishwasher a bunch of times. At first, we were making sure they went in the dishwasher's top rack only, but the kids have put them on the lower rack a bunch of times .. no problems.EDIT: Two years later, they crack. Whether this is due to the dishwasher or not, I do not know.I think the glasses are pretty durable, but I did drop one from about 2 feet above a hard counter, and it did crack. I think the glass hit at just the right angle though .. I think if you dropped it 50 times, it'd crack only once. I was unlucky.I will be buying more of these to replace all my glassware.EDIT2: I still like these glasses, but I think the dishwasher detergent "etches" them and now they look partially frosted/ugly. I've lowered my estimate to 1-2 years of use before they need to be replaced.

Absolutely love theses glasses, people using them didn’t even realize they were plastic. Hold up great in the dishwasher! Great size tooYear and a half later......Still love them but after a lot of top rack dishwasher use most have cracked or fogged. Definitely hand wash to make them last.

Clear plastic, doesn't look plastic. Washes nice in top rack of dishwasher.

These seemed to be a decent value out of the box for a few months but started to crack with normal use and top rack washing. I still have acrylic tumblers bought at Target several years ago and they have not cracked yet. These tumblers should be considered disposable and priced accordingly. As is, one star is too high. Very disappointed and unsatisfied.
