Ackers BORO3.3 Science Glass Measuring Cup-[Insulated handle | V-Shaped Spout]-Made of High Borosilicate Glass Measuring Cup for Kitchen or Restaurant, Easy to Read, 500 ML (18 Oz, 2 Cup)

Works great

I purchased both the 250 ml (1 cup) and 500 ml (2 cup) version. Basically, these are lab beakers with handles attached. They are consequently pretty thin, and my only long term concern is that they might be more prone to breaking than an old style PYREX cup. One strong point: they are very accurate. I actually checked both using a very precise scale. The 500 ml one was only off 2%, and the 250 ml one, a little less than 4%. My only reason for not assigning five stars is that they are a bit hard to read unless you have a white background behind them in use. They definitely could use larger and stronger lettering.

This little beauty is elegant and delightful to hold. Not a big clunky, heavy measuring cup. Absolutely love it. Yes I have to be a little more careful because of its delicacy, but it’s still intact and very useful after more than six months of daily use. Highly recommend.

I take care to wash them by hand as they seem so delicate. But they are used every week and still in one piece.

This measuring cup had all the features I wanted: red and black measuring marks, light weight, dishwasher safe, microwave safe, and a great spout. I heated milk in this cup in a microwave every day for 30 days. My microwave was set to full power for 2 minutes 30 seconds each time. After heating the milk, I emptied this cup and, for the first time (after 30 uses), I immediately placed a spoon in the empty cup and, to my surprise, the spoon caused a chip of glass to break off from the bottom of the cup! Video attached. This scenario may be a total fluke nevertheless very disappointed. I’d love to know the physics explaining what happened but it’s unlikely I’ll get an explanation. I immediately purchased a much sturdier Anchor Hocking Fire-King measuring cup to replace the chipped cup I had to throw away and life moves on.
