Review on Enhanced Tire Inflator: Central Pneumatic 68271 Dual Chuck with Dial Gauge by Richard Surveh

Precise manometer, valve opens gently. However, this is the only thing that worked. Usability is a big topic. The chuck requires a lot of force to seat properly on the tire valve and it doesn't bind like some others. It's not sustainable either. When I opened the valve when the cartridge was not properly installed (not letting air through) it became loose (the end of the cartridge that connects to the hose is notched and only pinched by a thin metal ring). After this happened I couldn't re-tighten it and now it was useless.
