Boulder Tools Heavy Duty Rapid Tire Deflator & Molle Pouch - Precision Release Button Air Down Offroad Kit - Glows in Dark, Bonus: Valve Caps, Cores, Repair Tool | Quickly Deflate 4x4 Off Road Tires

Not a dial and forget type. Bit of a faff to set up but ok when done. If different pressures are required for different terrain I.e. hard to soft or powdery sand or rock/mud you will need to set up different deflators for the different pressures then mark each individual deflator with the psi. No bar scale. Also the “hard case” is a pain because it is not stiff enough to work with the clips on the case. Spent a good 10 minutes trying to get them to catch and have only managed to lock 3 of the catches out of 4. 4th one is impossible to lock because the case bends so much.

Set them up as the instructions said but 2 of them continued to leak air til the tryes were flat

Complete with good instructions inside this deflation kit has all you need, 4 deflation vales, 4 replacement valve inserts, 4 alloy and 4 plastic valve caps and an 80psi tyre pressure gauge. The gauge matched the pressure reading that my stick gauges said and the case, although only intended for transit is completely usable long term.

Very good product for the money, easy to use and nice quality

I ordered these to use as deflators for my Jeep, to be used for offroad needs for lower tire pressure. I find the deflators to be nice quality, very fast, and about as accurate as a mechanical spring closure allows. You do have to manually set the final deflation pressure you want by manually adjusting the unit (and then you can lock it in with the included jamb nut). Once you lock them in, they are set but can easily be readjusted to whatever pressure you want. There are several good videos showing how to set these. It is as easy as it looks, maybe even more so. The included pressure gauge is accurate and well-protected by the rubber bumper, so hopefully will have a long life. The other accessories including extra valve stems and two different sets of caps, one set of 4 metal and another 4 plastic, are a nice addition. The case is not great as many note in reviews, but it will work for a while. I think these are a bargain all in all!

Desincha muy rápido y en una ruta 4x4 es ideal

Hacen de bien su trabajo y son fáciles de usar. Recomiendo revisar después de quitarlos que la presión que se busca sea la correcta ya que al usarlos la primera vez 2 de las llantas tenían un poco más de presión de la que se buscaba.
