I also had the previous model and was quite pleased. But the following model is processed significantly cheaper and needs some special attention. The battery compartment is not a "click lock" to find and use obvious but the battery cover is also the cover on the handle end. On closer inspection one can see a mark on the lid and handle, indicating the closed position. By means of rotation can unlock the tray and insert the batteries. So do as I loosen the screw and open by force ;-) What puts you in a manual, if the only useful information is not given ....? So if the student already designed the thing, but the product manager could drüberschauen least once. At least if one is sold as "branded" !!!
