I researched l multiple products before I have my purchase. Watched as many reviews as I could find on YouTube. I was told this is a "cheap" tool and if I want precision I should spend around $300. Well this tool works exactly as advertised. I've only used it on my dirt bike but not one complaint from me

I have lots of trouble trying to read and love compression gauges anymore. This compression gauge gets the job done at a great price! Very handy having the gauge as well as the adapters all in one storage case. Very easy to change batteries as well! Seems to be fairly accurate. Highly recommend.
