Very disappointed in this product. I confirm that the problem is evoked by Constantine. I bought the version with reel to simplify, but the result is the opposite. It is almost unusable. Finally I removed the tape reel in order to do my job. Surprised, because other products I have purchased from this company are of better quality. If not for this kind of work there is also this model (Tesa 58148-00000-00, ASIN B0053XWNLI) which is much better, cheaper and more compact.
