Very happy with this item. I installed it on the upper radiator hose for the sensor sensor. The hose clamps that came with it were great, they fit my 34mm hose perfectly and didn't leak at all. (I sealed the transmitter box with Teflon tape, if you don't your mileage may vary) However, as many people have said, the ground screw you see in the photo is missing. However, I'm not sure if I find that too problematic. To make sure the transmitter is actually grounded, I still want to route my wiring
