Review on Mastercool 89661 UV Aluminum Manifold Injector by Jeff Rhodes

I had to work with air conditioning and needed a set of good quality pressure gauges and I decided to try them. From the packaging they seem well made and easy to store. Case included. I preferred this kit over the cheaper one because of the manual fittings, sight glass on the manifold and the included UV dye injector. Connecting the ports and being able to adjust them manually helps prevent damage to the valves, which is a plus. All connections appear to be very solid, gauges are easy to see and read. The hoses are nice and long and comfortable. The UV paint injector is a nice touch and better than buying special paint cans or pouring paint into a hose. It's easy to add a winout dye that connects a complete sensor setup. Overall it seems like a good sensor setup with some very useful extras that make it worth the price.
