This tool really works.

I bought this tool to add some oil to my car's air conditioner. I replaced the A/C condenser and had to add some oil to the system which I had already drained. After adding oil to the tool, I connected the tool hose to the system and just slowly twisted the end of the tool to add oil. When the pen reached the bottom, the oil was added. That's all. Zeb
