Review on Fowler FOW72 520 767 X Proof Shockproof Indicator by Clifford Perez

Based on my experience, this indicator doesn't work as advertised. I bought it to monitor my tire pressure, but it failed to provide an accurate reading. The design looks sturdy but it couldn't withstand the harsh terrain of my daily commute. The only good thing about it is that it's shockproof. However, that doesn't make up for the fact that this product is a waste of money..
