Love the size and convenience they provide.we love themThese cups do not hold up to condensation. After about 5 minutes, the outside of the cup starts to disintegrate. Do NOT use these for cold drinks. They seem to be ok for hot drinks, but they don't keep the drinks hot for very long.The cups alleged they are usable for hot beverages and cold. The cold, if left sitting the cup withers. If hot,the cup is too flimsy to feel secure. My experience is short and maybe doubling the cups will fix the problems.These are quite nice cups. A bit difficult for me to separate, but I have loss of strength in my hands. I’ve used these cups for hot beverages as well as microwaved egg breakfast cups. They’re a bit tall for breakfast cups if your only doing 2 eggs + add ins, but they work. Perfect for a couples breakfast cup to share or a tall frothy beverage.So far just 1 cup leaked slightly (just a drop of egg white) at the seam when microwaved, but that was the only one out of more than 30.I love the size of these cups, they are very comfortable to hold.One thing to note - these cups will only fit in my Keurig K Supreme Plus if I remove the drip tray from the machine and tilt the cup to nest the bottom in the drip tray. Not a huge deal, but you can’t make a full-to-the-rim cup of coffee since you need to be able to tilt the cup to remove it after brewing.I really love this cups. They are 20 oz and perfect for holding hot tea. I would definitely recommend.It's cups.They are nice and sturdy, well packaged in ldpe sleeves. Very high quality cups and plenty of them.
