If like me you live in a cold climate and winter temperatures can drop below -20C, there's nothing worse than sitting in the cold to check and inflate a tire . This is a find! It's not winter yet (yet!), I know it will be very handy. I immediately unpacked and tested the product. It was so easy to use that I didn't even need to use the manual. As soon as I connected it to my bus, it read the current PSI. This is much easier than manual gauges. Very happy with this compressor. I look forward to using it in my closed garage this winter!
