Review on 📏 Precision Measuring Made Easy: Rotary 15344 Archer Digital Engine Tachometer for Echo by Josue Zepeda

I work in a small engine shop and had the "Echo" version replacing these and I had them for 10 years no problem. It works the same way and I was happy with my purchase for the first two weeks until a little carb cleaner accidentally got on it and melted the body. I pointed this out to them and they told me I could return it. What I was saying was that it's meant to be used in small engines and that chemicals like carburetor cleaner are used in those things all the time! This had to be decided before the production process. My Echo One has been exposed to many chemicals over the years and this has never happened. Be careful when using this in professional applications.
