Review on WirthCo 94494 Galvanized Measuring Thumb Operated by Tony Ledbetter

This measuring tool did wonders for my oil system maintenance routine. As my tests showed, it’s accurate and easy to use even with just one hand. The galvanized material ensures durability, something that’s important to me. While the measurements are in quarts, it would have been nice to have a smaller increment for more precise MEASUREMENTS. Overall, I’m pleased with this handy thumb-operated tool. .
