This drill / driver is well suited to small daily work such as screwing or unscrewing pack furniture or drilling holes for hanging pictures or the like. For cons, I do not think it is best suited for heavy or complicated work such as drilling of a large series of holes in reinforced concrete (although hard ..). Besides, I think it is of benefit to be considered a screwdriver / unscrewing than a drill. Its advantage lies mainly in cord length, ie 6 meters, which eliminates the need for an extension and especially to face the recurring problem of storage devices, ie they are never loaded when it needs and that it is used only occasionally. It is delivered in a house in fabric inserted into a cardboard box with handle serving as "suitcase" of transport. The kit includes the unit and a set of drill bits and screwdriver heads. Overall I would say this is a device designed more for occasional use as a truly pro use. Otherwise, no complaints ... it works.
