Review on 🔍 WirthCo 94120 Funnel King Graduated Measuring Container - 500 ml Capacity for General Purposes by Dana Bennett

The container is well built and has a physically convenient design so I bought it. But the gradations don't add up mathematically. For example, on the US side, the first label is 1/4 qt. The next label is 1/2 quart. 1/4 quart is 8 ounces and 1/2 quart is 16 ounces, but there are 13 graduations (marks) in between! From 1/2 quart to 1 quart (16 oz) there are 25 of them! The markings between the labels are completely useless. Similar problem on the metric side between 1/4 liter and 1/2 liter but then everything is fine between 1/2 liter and 1 liter. I just called the manufacturer's technical support (Wirthco Engineering) and they confirmed to me that I was right! It's made in China so they said it would take some time to fix it. I wish it had ounce markings on the US side and ml or deciliter markings on the metric side.
