This feeler gauge is a fantastic tool for anyone who regularly works on vehicles. As a result of using this product, I found that the measurements were accurate and the tool was easy to handle... The BLACK color is a nice touch that makes it easier to locate in my toolbox. The only drawback is that the gauge could be a bit thicker to make it more durable. Overall I highly recommend this product for those in need of a reliable feeler gauge..
Pros
Provides accurate measurement for proper spark plug gap, leading to improved engine performance.
Cons
Requires some skill and knowledge to use properly, which could be a barrier for novice mechanics.
Photos are deceiving. The device must be strong enough not to deform under load, which explains the size. It is approximately 6 inches long, 1 inch high, and 1.25 inches wide. So a little more to scale than it appears on the website.
