Insert - 6 !!

DC vornweg: I am an engineer and if I had constructed this device would my boss said to me: Nice thought but completely misses the point !!!
And the idea is actually not bad. The slant of and push down the the label rolls off nicely on the CD, and will not wrinkle or bubble.
Unfortunately, however, fit the labels themselves not work properly on the device on it, trying for example to pull the lateral notches of the label tabs on the corresponding pins on the device, this usually rip off. The dimensions of the label and device simply do not match! For this also happens that the slightly raised center ring on the device does not fit into the holes label - minimal too big, just so much great that it is impossible to center the label at least as - can not.
So I personally can only advise against this unit, completely frustrated I bought the slightly different working unit from Data Becker and behold: This works much better, even with the Avery labels!
