Review on 🛠️ BETOOLL HW0130 Cylinder Compression Gauge for Automotive Engines by Brian Douglas

Lots of connection options. The hose and tip feel well made and durable. A pretty good guide is included that pretty much matches what the knowledgeable folks on the car forums have suggested. The pressure gauge keeps the pressure reliable. So if you do the tests yourself, you can start the engine from the driver's seat without worrying that you won't get an accurate reading when you get out and check.
