Review on Innovative America 7862 Grease Joint Rejuvenator: Unleash Superior Performance by Tim Pulse

I bought this to free up 2 oilers on the bottom pins on my Kubota supercharger. These pins are located at the bottom pivot point and will catch on dirt when working with the loader. I couldn't put the lube in either, so I ordered this tool. I followed the instructions and filled the tool with penetrating lubricant. I placed it on the fitting and started tapping the tool to inject the penetrating oil. Oil has not entered the fitting. At some point the fitting in the tool broke. I repeated this on another pin with the same result. I then tried a fitting that I knew wasn't frozen. He squeezed a small amount of penetrating oil into the fitting. The tool is expensive ($50) and cannot free a frozen fitting. I would not recommend it.
