Good quality product, well packaged.
Good quality product for a small price. I used it once on my lawn mower engine and hope I never need it again; but I have it just in case. Well packaged for easy storage.

Nice tool, well made
Very nice tool. For the price, a compression test tool like this is a must. Been working on golf carts lately and the attachments fit any and all spark plug sizes. Gives an accurate reading of compression and the condition of the cylinder rings…first thing to rule out in the life of an engine. You don’t have to crank this in, hand tight works fine. So far I’ve tested my Echo chain saw, Echo leaf blower , Honda power washer, Honda ATVs, EXGO golf cart and Gravely lawn mower. Simple, easy, accurate and a great diagnostic tool for the shade tree mechanic in your home.

Cheap but very good and lots of adaptors
No complaints and the price is incredible. Works absolutely fine on a 2017 Mini 3 cylinder engine. This engine has a very narrow spark plug hole so I thought it might not fit but the selection of adaptors included one that did fit. It feels decent quality, maybe not super accurate at this price but as a ballpark and for comparing cylinders it's spot on. If you can remove spark plugs then you can use this, it's super simple. The case is handy to keep everything together and clean. Very happy wirh this item and arrived next day as promised.
