Review on Accurate Measurement with Glass Measuring Beaker 100Ml Graduated: Empower your Precision by Kevin Taharka

My wife and I use them for various purposes in the kitchen. I mainly use them for heating/cooling brew liquids. I didn't go above 210F but I heated them to that and quickly chilled all 5 glasses. I have 5 whole glasses left. I can't speak to the accuracy of the measurement markings but they appear correct, I'm not doing anything that requires an extreme level of accuracy. I would highly recommend this set as it has a good selection at a great price. Now I'm kicking myself for not buying 2 sets. Remember to always practice safe glass handling practices with all glassware!
