Review on MR CARTOOL Manifold Refrigerant Conditioning by Robert Aiono

This device is well built and does everything as promised. It has excellent features, the display is easy to read and the backlight is pleasant. I had to work with 4 different refrigerants and this one worked well with all 4. It was as accurate as any of my other gauges, and its small size was a welcome change. and coincidence, but that was all. As I said, he performed well and did everything that he felt would be very valuable.
