Review on High Precision Digital Tire Inflator with Pressure Gauge (250 PSI) - Air Chuck - Digital Air Compressor Tire Inflator Attachment - Accurate Air Pressure Gauge with Inflator - Tire Inflator Nozzle by Justin Hill

I've been arguing (with myself) about getting a digital or analog version. My main dislike for digital is that it usually requires batteries. The issue was resolved when I decided to remove the batteries during long periods of non-use. I was amazed at how easy and quick it was to get the right pressure in each tire, including the spare. My only caveat is that the LOCK-ON AIR CHUCK be seated securely on the tire valve before it locks up or it will have a small leak resulting in improper tire pressure. Otherwise it works like a charm and is exactly as advertised/described. Very satisfied with the product.
