Review on Actron CP7828A Professional Compression Tester by Kenny Noel

Revainrating 4 out of 5

Works well, but beware!

As Lyle Josie pointed out, adapters can get stuck in the motor and cause problems. This happened to me when I first used the device. The solution is to make sure the adapter is VERY tightly bolted to the tester (you can even use LocTite if you don't plan on using other adapters) so it doesn't come loose when you unbolt the entire assembly from your engine . Other than that it seems to be of decent quality and worked great for checking compression in my S2000 F20C engine.

Pros
  • Great for a small home
Cons
  • Questionable purchase for the elderly
