Correction Roller fulfill their purpose - but not optimal. They have just about everything you need: A reasonably good handling, a huge supply of tape (eight meters after all) and a rotatable cap. However, I have been more favorable such products held in the hand, which could be better grab something and run. The cap is at other scooters up a notch far better. Here they can be turned over the top by a rotating mechanism forward - forward it still remains open, so that for example in Chaos pencil cases that are full Buntstiftanspitzreste, mixes everything but.. Okay, this is obviously a mess example. Nevertheless, I find other variants better in which to forward directly a small cap can be put on, which then also really clean closes (the advantage here of course is obvious: The cap can not be lost).
In applying these scooters can halfway points. If you get the handling, it works most reliable and has few dropouts, which overlaps the tape, or it does not hold back or redeemed directly from the sheet when placing the scooter. This happens, however, with other scooters - there but something rare. On paper, it can be - as long as it is completely dry - good overwrite (whether with a pencil or pen). When copying it remains invisible.
Thus, the product fulfills its purpose - with small losses. Something I was satisfied with a product from the same manufacturer. With the Mini Pocket Mouse, but offers only five meter band.
