AN Brand Bottom Mounted RO Pressure Gauge

BUYERS BEWARE!!! I got a 100psi pressure gauge while all the pictures for the listing say its a 300psi gauge. Product shown in the image has the pressure socket at the back and can be panel mounted, but its a normal one with the socket at the bottom and hence cannot be fixed anywhere. Also the glycerin level is too low, only a half of the meter is covered. Apart from that there are slight damages to the thread and the socket (not sure if its during their testing, if any or when its "used".)
