I have tried many tacky roller and struggled repeatedly with it.
1. The band has become so entangled or stuck that one could no longer rerolling. This means that the part was just ripe for the garbage. Very annoying when that happens right at the beginning.
2. When applying the adhesive layer was not on paper but remained on product liability. Ie unused tape was wasted.
At tesa Glue Roller comparable to me has never happened. The tape can be cleanly and accurately roll, just as it should be.
The Glue Roller are very handy for all the possible connections (paper, cardboard, photos) that depend on accurate, umkompliziertes and especially clean gluing.
The tape adheres very well and is highly visible to double "brushing" to avoid the reddish color. Do not worry, you see it not, even if one sticks on white white paper.
Very convenient and easy is the refilling. The housing can be both for the two tapes are used as well as for the correction tape from tesa (permanent + removable).
Conclusion: Finally a Glue Roller of his money's worth - 5 stars!
