Review on 🔧 WINMAX TOOLS AUTOMOTIVE: 16PCS Professional Diesel Engine Cylinder Compression Tester Tool Kit Set w/ Case – Ideal for Auto, Tractor, Semi by Kaushik Sokolowski

This tester works very well. And it has adapters that fit almost any engine. However, it may happen that you have to pull out the injector instead of the glow plug. I don't really care as I bought it for use on emergency engines that have already been removed and have an engine stand already installed. Note, however, that specifically for the GM 6.2/6.5 you will need to pull the injectors instead of the glow plugs. If I had to change something about it. This would be the mentioned lack of all glow plug adapters. And I would double the hose length. Aside from those frankly picky things. This works very well. That's why it got 4 stars
