Review on 🔍 Highly Accurate Topeak Shuttle Digital Gauge: Measure Pressure up to 300 PSI/20.7 BAR by Jason Unruh

I bought this sensor to use with my mini pump for home renovation on the go. I thought this would be a great way to quickly see how much air pressure I was pumping into my tires without having to remove the pump and check with a separate pressure gauge. For this purpose it works great. What disappointed me is that when used without a pump just to check tire pressure it releases a large amount of air when removed from the valve. Even when used as a standalone pressure gauge, it does not retain the recorded pressure when disconnected from the valve. This is an expensive gauge. I can't understand why he's having these problems.
