Review: Excellent quality, large assortment, highly recommend. - I work on heavy duty ag equipment and often don’t have the correct gauge, fitting, or adapter, with what I’ve cobbled together over the years. Having this kit solved that issue. It is great quality and I haven’t had any issues with it for the year I’ve had and been using it. I’ve never ran into a situation now, that I didn’t have what I needed to test pressures. This kit functions flawlessly and fits nearly all applications. This is a great value for the money considering what tools trucks are asking for half this set. I highly recommend to any mechanic or diyer that works on any sort of hydraulics.
Review: Worth every pennny. - Very nice kit. Good quality. Absolutely nothing bad to say about it. I've used it 3 times without issue so far.

I like the case, keeps the gauges in a safe space to ride around in the service truck. They seem to be of decent quality for the price point, all the gauges worked right out of the box with no issues. I haven’t used the run tee’s but it does come with the Parker quick coupler.
