On the whole, the unit is ok

The slide carriage is suitable for glass-mounted slides to a thickness of 3.2 mm. Younger slide frame (without glass) but are much thinner, so the thickness can be adjusted manually in 3 stages. Nevertheless, I always use the setting of 3.2 mm, since the carriage otherwise is very difficult to push. In the vertical reservoir approximately up to 15 thin slide frames fit (without glass). This is very handy. However, the slide magazine for 4 Dias is a few millimeters too wide fall, so that it can only be inserted by force. Even after the filing of 2 mm, it is still difficult to move! This led to the devaluation.
