An injection device comprising a housing with a receptacle for the product, a dosing mechanism for setting a product dosage to be administered and for displaying the set product dosage and a dispensing mechanism for dispensing the product. The dispensing mechanism may include a piston rod, at least one sleeve rotatable relative to the housing to eject the set product dosage, and a button moveable relative to the housing and relative to the at least one sleeve in the dispensing direction from a dosing position into a dispensing position to eject the set product dosage. The device can further include a first detector for detecting the position of the button relative to the housing or the at least one sleeve, a second detector for detecting rotational movement of the at least one sleeve or a component part coupled to the at least one sleeve and a feedback generator mechanism.
