Saw this at Coles Coorparoo, Brisbane. And might be available in other stores.
Bought one and checked it's accuracy with a digital gauge and it's on par with the digital's readings.
Features,
*Measures 0-60 PSI
*Magnetic backing firmly holds to metal surfaces
*Protective rubber casing
I grabbed one of these at Coles too… looks like decent enough quality compared to some of the fiddly plastic shockers sold at SuperCrap and RipoffBarn, and for $2.25 you can't lose…
