Do not do 28

This portable compressor for tires, which nevertheless has a good flow, suffers from a very annoying limitation: you can not measure the pressure during inflation. This means that to inflate a tire to the desired pressure it will take over inflate "by eye", unscrew the air hose from the valve of the tire pressure measurement with the small detachable manometer, and then repeat until we guess the right pressure. Ridiculous. Someone says that this limitation is due to approval issues, but if it was true all other compressors with online pressure gauge would be outlawed ...
Besides the small gauge with its elongated shape is difficult or impossible to use on some scooters with large disc brakes like mine (Piaggio X9).
In short: avoid.
