Maybe it's the color, maybe it's just a coincidence ....
I unpacked and took advantage of both the Greens first. The first signs were still covered perfect (about 4 cm). After about 3cm blank tape looked out. Using a screwdriver, I wrapped this back on (the take-up reel has a corresponding recess to). After repeated use of the same game: Again the (empty) belt looked out and there was nothing covered on the document.
I've tried a lot of use with wrap and again. The result was that in the end about 10cm band (some empty, some still coated) looked out and a wrap was no longer possible, since demolished. The part wandered into the garbage ...
Now even the Blue remained.
This worked, up to this review, relatively reliable. It covers, on white paper, cleanly, can be described again and again this can again cover the new label. Nevertheless, it remains a bad feeling because here several times from the white masking "left" remained (too much on paper) and also the screwdriver had to be unpacked before to tighten the belt again. Actually, I expect at any time so that the rolling stops working well here properly.
Frankly, I have no confidence in this "micro-Tapes".
