Review on CATOOL Manifold Automotive Couplers Recharge by Darnell Nahabet

You get what you pay for. I bought this and a cheap pump. Both worked once. A vehicle does exactly what it is supposed to do. Along with the pump, I did not pull the vacuum on the second car. So I bought a better pump and it didn't work. Then I bought a new set of pressure gauges and everything worked. In my experience, once it works very well, I would suggest a better product several times.
