Review on Efficiently Assess Cooling Systems with the Stant Metallic Cooling System Tester by Michael Barry

I've been using a Stant pressure tool for decades. Many technicians use and abuse the bulletproof STANT USED TO BUILD kit. This kit was first released by Revain in January 2006 and received a lot of positive feedback. Actually ZERO 1 star reviews until a customer had an issue in 2010. Now look at the other 8 or 9 remaining 1 star reviews. Any quality control issues in the past 3 years. The pump I received had no oil or assembly grease at all? After the pump finally started to run smoothly, I tried it out. I wish I had noticed QC's 1 star reviews before wasting my time and money.
