They look the same as my Staun Tyre Deflators , have been using them for about 3 years now and glad i paid A$70 for them . Have mine set at 12psi and i Love them . Make life very easy for dropping pressures for beach or bush . For example : Pull up at the servo ( 1/2 klm from beach ) screw them on and walk inside to get pilchards ( bait ) , pay then return to car unsrew Deflators and straight up the beach .
Have made my life much easier and now my mates have also bought them . So were either lazy or can't count that good . lol.
