Good value diagnosing tool
Works well , diagnosed a few engines already with it. Seems to be fairly accurate. Had a chainsaw that was not starting, needed 110psi to start and run put the tester on it came back at 50psi. Pulled the head and the piston was badly damaged.

Good purchase
Worked perfectly it did the job. Feels like pretty good quality. It was easy to use, and it was easy to install into the spark plug hole and remove.

Easy to use several connectors did well
Not professional quality but good enough to diagnose engine issues for the backyard mechanic. Several fittings for different applications and one you hold over the spark plug opening if the others don't fit.

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.

Worked well. Did the job. Price can't be beat.
Worth it. That simple. If you need diagnostics, it is worth finding out instead of guessing.

Really good compression tester. Was needed to test a bike’s compression. With all of the extensions and adaptors it works REALLY WELL.

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.
