Review on Lisle 15190 Valve Core Tool by Darryl Jennings

Lots of confusion about how this device works. I wasn't impressed with the tool when I first got it because it didn't feel like it was setting just the right amount of torque. After lots of experimentation, talking to Lisle this week, and testing my instrument on a delicate scale calibrated to inch-pounds, I have come to the following conclusion. My tool is fairly accurate and reliably breaks at 4 inch-lbs when used properly. And that means you have to turn the handle of the tool until you hear a clearly audible CLICK. It's actually quite loud (and you can feel it in the instrument). However, if you work in a very noisy shop, you may experience hearing problems. When the tool clicks on the mod, its internal clutch REALLY slips and you'll know you've got up to 4 inch-pounds of valve torque (trust me, I've measured this 20 times in a row and it hits the mark every time). It's a very nice and useful tool, the best I've found out there for properly tightening valve cores. The instrument's red body is marked "USA" in case you're wondering where it was made. IF you use the tool correctly, you will NOT confuse CLICK with anything else. He's so strong and clear. One slap against Lisle is that they did NOT include instructions on how to use this tool properly in the packaging. If they spelled out what I'm telling you here, they would have many more satisfied customers who wouldn't be ripping off a nice black pen or ranting about a tool that didn't work or was junk because it didn't work. know how to use it. Maybe Lisle should have more space to explain how to use the tool properly and less space to translate her crappy current instructions into three languages, right?
