Review on Unlocking Efficiency: Introducing the Lisle 19700 Valve Holder by Eric Hanson

I was very disappointed when I first opened the box. it was MUCH smaller than I had hoped. The way they crumpled everything up really made the deal look sour. I opened it up and untangled the short tube - it wanted to curl up again. They say there are two fittings in the kit, but it's actually one with a step for two different thread sizes. I stared at this thing and noticed "Made in USA" written on the hose. In fact the hose was quite thick and things I didn't like started to look like good ideas: A short hose is better than a long one. There is no swivel so you can just screw it into the spark plug hole. of course not! You will connect it to a hose and this connection will act as a swivel. It's also a good idea to have two thread sizes on one adapter. who still needs a collection of adapters in their toolbox. short threads make it easy to put on and take off. The more I looked, the better I felt about my purchase. these guys know what they are doing. a good product.
