Review on Lisle 19860 Tire Deflator by Bryan Cavalcante

I've used them several times to deflate tires. They work quite well and are easy to use. Even ventilation is ensured by a small pin that pushes against the valve stem when you tighten the deflators. 4 things. you can easily measure the air pressure on all tires at the same time. I plugged in one, counted 15 seconds, and started the second. Continuing at around 1:30 am I was knocked out from 35psi to 20psi. Went like clockwork. Simple, no moving parts, easy to install and remove. Durable material and they don't take up much space.
