A very good lighting when working in unlit areas. Good food sustainability in the use phase, following the battery used. Practical, L-Boxx ensures storage of the charger and other small tools to the type of work to do. Solid and easily transportable, it suffers no fragility (well protected LEDs). Four stars, since there is no existing adapter which also provides the use of a good accumulator of the large public that green range of professional blue range. Yet this small interface could easily be performed by Bosch and should not be very expensive; it would make life "DIY" of many.
