We love the price of these cups, but they don't fit our trays very well. They get stuck and are hard to get out of the tray without the cup breaking. If they could be a little more slender, they would work perfectly.
We've never used these particular cups before, but I bought them because of a good price offer. They work VERY well. So easy to separate with no sticking together like some cups we've used before. We've already bought more, and will definitely use them again.
