Review on 🔵 Mastercool 89660-PRO5 R134a Manifold Gauge Set in Blue by Lance Story

Good set of pressure gauges. It works and the sensors don't vibrate. I don't like clutches as I prefer ones with flywheels that open the Schrader ports once the clutch is in place. I will order a different type of clutch but not from Revain as Revain charged me a restocking fee when I returned a defective distributor from another brand. And an update. The high-pressure side adapter leaks badly and is unusable. Well I was able to use this clutch once and now have to order another one. Again, I'll do a little work with the 134a system and either skip the high-side monitoring or borrow a coupler.
