Freeman digital tire inflator with LED works as described. Tire maintenance is now as easy as plugging in the Freeman, checking the pressure, pulling the trigger to top up with air, and deflation of the excess when needed at the push of a button. Another nice feature is the backlit LED display. The only thing that doesn't work perfectly is the clip to keep it on the hoop. I have it slightly off center but if I center it first it works fine. To be honest I'd rather keep it because it's so quick to check and fill a tire. It looks like a well-made tool for the price, but I can't tell how long it will last in a mechanic's shop. So far I'm doing great.
