I have "507 Dahle" received today and the supply of Amazon as always was super fast. Before I decided to buy, I have of course read the reviews it. It is often written by a problem with the "right angle", the device can not cut properly. So I already prepared for everything and a screwdriver set ready to make an adjustment, as described in some reviews as problem solving. Add to that a useless and a photo page normal printer paper as test objects. Unpacking, setting angle angelegt- perfect !!! It must be measured and to identify any deviation. Photo cut- clean cut, even when I cut a fine about 2 mm wide strips. Printer paper also cut without any problems.
Either I was lucky or Dahle has recognized the problem and Dissolved "Made in China" it is but still.
Perfect device and I am fully satisfactory in any case after the short and rapid test.
