Review on Lang Tools 401 Deflator Location by Rob Sanchez

I found this misleading. I figured I'd get a deflator that would allow me to drop the air pressure from 28psi to 15psi off-road. They don't. They are not adjustable. You're just deflating your tire. I'm not sure why you need something like this if you just want to reset psi. If that's what you want, this could be for you, but don't be fooled like me.
