I was very excited to get these graduated cylinders at a great price, and when they came in they were very great looking quality! After using them twice to make a compound, I realized that they were not measuring accurately after pouring the contents of the compound into an 8 oz bottle and coming up short. I then went to my automatic water dispensing machine and dispensed out the max quantity listed on every graduated cylinder and as you can see in the picture, every cylinder ended up showing a measurement over the maximum quantity. This supports my previous statement that the listed measurements on each cylinder are in fact inaccurate/short on their listed measurements. Clearly this has something to do with the manufacturing of the cylinders, and I'm not sure if the measurements are listed inaccurately or the diameter is inaccurate. Never the less if you use these cylinders you will not be getting accurate measurements, but ones that come up short regularly.
