Review on MASTERCOOL 89661 PRO Manifold Aluminum Standard by Brad Collins

Received these gauges on Saturday and have been working with them for a few days now it's Wednesday and the gauges are working fine, the hoses and manifold are great but if you have the same coupler how i get then throw them away. Take away and get some higher quality clutches. These couplers flex shredder valves and my coupler on the bottom doesn't pass freon or collect vacuum so I gave 3 stars because one of the most important parts that should work really well was out of order, I'm now replacing plugs with Robinair plugs , hope they do the job.
