Are you talking about the little brass ones? If so, I've found them to work about 70% of the time. For the cost, I think they're worth it but definitely not 100% accurate. But realistically, there's no need to have the perfect number every time in my opinion. I think there is a decent range of pressure (within 5 psi of what you're aiming for) that will work just fine. Like Sgt_USMC said, you just put them on, shoot the shit with your buddies, and then remove them when they stop hissing.I currently use an ARB deflator and it works as intended.
I’ve seen some ads about preset tire deflators. Does anyone here use them? Pros/Cons?
I will agree with you on not being totally accurate but they do come within a few psi. I have my deflators (forget the brand) set to 12 psi and they would usually end up around 8 when all said and done.Are you talking about the little brass ones?

I have mine set at 15psi (no beadlocks) and they almost always end up within about 3 psi. But twice one of them stuck and kept leaking (not sure if it was the same one of course).I will agree with you on not being totally accurate but they do come within a few psi.
