Review on 🔧 Actron CP7827 Compression Tester Kit: Reliable Engine Performance Measurement Tool by Jeffrey Kue

Product works as advertised. BUT; Take another second to tighten the adapter onto the hose. Otherwise, after screwing the adapter into the head, the hose will unscrew from the adapter, leaving the adapter screwed into the head. With most engines, you don't have room for an outlet around the adapter. I had to apply CA to the threads on the hose, screw it back into the adapter, let it dry, then unscrew the adapter and head. It was an easily avoidable headache. Simply place a wrench on the adapter and tighten it onto the hose. It could be better, but overall it works as described.
