I bought this to replace a heavy duty Rhino USA tire pressure gauge I had loaned (apparently given) to a friend. I love its strong, durable materials and construction very similar to the Rhino and found it just as accurate and easy to use; However, upon lifting off the tire valve, the Diniri Heavy Duty gauge immediately hisses air and the pressure needle goes down, requiring me to hold the gauge in place on the valve stem until checking the pressure. Maybe it's just a rare, broken piece of equipment, and most hold up well. Unfortunately, I didn't check the sensor until the next day after the return period had expired. Maybe I can swap it out with a friend of mine who has my Rhino, or if not I'll just buy another Rhino USA gauge. — Update 06/25/2021: I unscrewed the tip, removed the spring and valve disc, wiped and blown. They were removed to remove all grains of debris and reassembled. Now the pressure gauge works perfectly; holds pressure after being removed from the valve stem. Thus, the device had no defects and required only little cleaning.
