Pyrex measuring cups are valued for everyday kitchen use, but the main draw here is the familiar glass set rather than standout performance. The cups are described as fine for basic measuring, and the 2 cup size gets regular use. The biggest knocks are poor pouring, with the 4 cup especially called out, and markings that wear off quickly. Durability is also questioned after a 1 cup shattered in the microwave. The warehouse price around $11 makes the delivered $16.99 feel less compelling.

  • Home cooks measuring liquids daily, because the cups are easy to use for routine prep when durability and markings hold up.

  • Bakers who want a glass cup that can handle hot and cold ingredients, because borosilicate versions offer strong thermal shock resistance.

  • Shoppers replacing a worn measuring cup, because the set covers common sizes and the markings are the main wear point.

  • Cooks who need a clean, accurate pour, because this cup style pours badly and the spout design frustrates transfer.

  • Anyone who depends on long-lasting measurement marks, because the etching and ink can wear off quickly.

  • Microwave users heating water in the cup, because the glass can shatter after brief heating.

Everywhere but North America Pyrex is still borosilicate. We get the crappy soda-lime glass. It's garbage.
You might consider getting borosilicate lab beakers. Available in 250ml, 500ml and other sizes. I salvaged my 250ml from my parents' house a few years ago.

I have a couple of regular uppercase 2-cup measuring cups and pretty much use them daily. A 4-cup lowercase version I bought later is way too heavy to use over a stainless steel mixing bowl.

The Pyrex Griffin 250mL Beaker is made of borosilicate glass. This material offers excellent thermal shock resistance and mechanical strength, making it safe for heating and cooling.

Not sure what the difference is between the USA/No. 1000 beaker that I have and some of the 1003 that Amazon lists.
Check your lab supply store, too, where it might be cheaper.
