Door Pressure Gauge by GordonGlass

For what it is I don't believe it to be worth the money, however because of supply and demand I would charge what I paid for it - I needed one for work to test some doors and I was limited to where to buy one and of course amazon had one. It does what it's meant todo, shame it doesn't have a hook for handles. Not the end of the world. It's small then I thought but thats better as I can just put it in my pocket.
