High quality sensor. It seems accurate compared to my other sensors. Feels good in hand as it's heavy/solid. Aversion to other sensors with blunt rubber tire spikes radiating around them. However, nowhere in the description does it say it won't hold any pressure. Why doesn't it hold the pressure? I started the return process but later while packing I saw "holds no pressure" written on the package. So I decided to leave as it is not broken and tidy.
