product good, shipping package was lacking, box was crushed thankfully the product was ok.

Nice to have a quantitative way of determining if a motor is reaching specified rpms. Listening works kinda, but being able to document precisely for future reference and comparison is great. Love the non-contact capability. Recommend!

The product works as intended. It’s convenient to hold near the plug wire.

Very helpful for obtaining accurate (wireless) rpm data. Good thing too, my previous ‘estimate-rpm-by-ear’ method resulted in both idle and high speed settings that were smooth but much too high.
