Finally an economic product and small size that does what it promises: a tire inflated to the desired pressure. Simply select the pressure value on the LCD screen using the two buttons + and - in stages of 0.05 bar, and the compressor will stop automatically once this value is reached. It can also be used manually, by pressing "M" and playing in that case with the power button. Unlike other similar products (Michelin ...) the pressure is measured directly and during operation of the compressor, always with a precision of 0.05 bar (5 kPa). The re-inflation of a tire to add a few tenths of a bar is done very quickly. To inflate a flat tire there must be a few minutes, being careful to overheating (always observe the operating times / rest provided in the instructions). We have the choice between three units: psi (pound / square inch) for the barbarians kPa for scientists and bar for us. A custom bag can wander with flexibility; the cable is wound around the base and fixed with Velcro. The air hose is hidden it in a receptacle on the back of the unit. The small dimensions allow to put it under the seat in scooter, for example. Only downside (besides the noise, common problem on this small compressors) the fastening system of the hose to the tire valve: it is screwed, while I would have preferred the fast system with spring. We will have to verify their quality over time, as these devices a curly China sometimes have a rather short life, set the goal of some inflations all goes well, for now. In summary: great product for ergonomics, price, reduced dimensions and thus portability. Good flow. Very noisy. Reliability check in time.
