My analysis of this tool showed that it’s a must-have for every mechanic. Its striking purple finish makes it easy TO find in a toolbox .The extension has a strong and durable construction that can withstand the wear and tear of everyday use. The extension helps you easily access hard-to-reach lug nuts and bolts in tight spaces making tire changes and repairs much easier. However, its only 4 inches long, which may not be enough for certain vehicles with deeper wheels..
