They claim that it gives a little inaccurate reading of the pressure on the indicator (0.1), but it's difficult for me to verify this. Has some pros: In overall, a good device. Comfortable, with a reasonable amount of weight, and relatively silent. The digital pressure gauge is another feature that contributes to the overall level of convenience. When the predetermined pressure is reached, it turns off by itself automatically. This previously established pressure is still fresh in my mind. Got cons: Possibly not the most space-efficient piece of equipment, but this is intentional on the part of the designer because the compressor is instantly placed inside of a metal box. Given that the fabric handle is already present, I would also like to include some form of lightweight fabric bag for boxing or something similar to a braid. I have it stored in the trunk, along with other items, in a toolbox. I recently fashioned an improvised container out of bubble wrap for it to ensure that it does not get scratched and that it does not beat.
