It feels like professional lab equipment. The double chamber design really helps prevent wrong readings. Comes with a sturdy case for safe storage.
This device is tough and well-built. It gave me a definite answer on my old 4runner’s head gasket issue. Not the news I wanted, but I trust this test completely.
Testing for a blown head gasket was a pain before, but this tool made it clear. It changes color only when CO2 is present. No false positives. It saved me hours of troubleshooting.
Setup is easy and quick. Just fill the chambers and use the bulb. The color change happens fast if there is a problem. It’s a simple way to avoid costly misdiagnosis.
I was skeptical at first, but this tester is solid. The rubber seals hold up well and the fluid lasts a long time. I’ve used mine for years without needing replacements.
