I've wanted a medium graduated cylinder for a long time, but this set gives me a huge range of measuring cups for all occasions. I use them for precise mixing of small amounts of concrete. The largest flask has a 1 liter capacity so I can measure up to 7kg of concrete and for micro batches I can use small graduated cylinders. I'm sure there will be many more uses over time, but for $10 just mixing concrete is worth it.
