Review on ZUYEE Silicone Measuring Cups (2 Cup + 1 Cup) - Flexible, Stir, Squeeze, Pour Baking Cups - Dishwasher Safe, BPA Free - Ideal for Coffee Maker, Butter, Chocolate Mixing, Plaster - 500 ML + 250 ML by Shari Smith

They are great, I use them almost every day. I got the 2 cup version as a gift and loved it so much I ordered it to have spares for when the original is in the dishwasher. One cup fits into two cups to save space. Best for items that squirt freely when dry items are poured into a small opening (sugar in a bottle, salt in a shaker, etc.). It's no good if you throw in something like flour that doesn't move as freely. Liquids are great, I've used them for a variety of things e.g. B. for measuring hot water for jelly (careful!) and for mixing and pouring batter for pancakes.
