Solid, stable, very good

In general:
I think there is no better model for the tape. The model can be in my opinion, very simple and easily operated with one hand. Since there are so many votes against this, I want to look at the times completely differentiated (ridiculous):

1) The end of the strip glued in front of the incisors.
2) strip is easily within reach with your thumb and forefinger - no Abfriemeln from the roll
3) I loosen the adhesive contact and pull the strip
4) I can "counter" with the free middle finger against the housing to prevent displacement
5) With a slight downward pressure against the cutting teeth, I disconnect my piece from the remaining strips
6) The rest strips automatically sticks again in front of the cutting teeth
7) Do I want to pull off a long strip, so this is achieved without "counter finger" problems

I do not see where there could be problems. The model is designed prima my opinion:

Pro:
+++ Extremely difficult - does not lift easily with one-hand use from
+++ Practical, well thought-out shape - stripes tangible strip not flying around
+++ Sharp teeth for simpelstes severing the strip
+++ Simple appearance in elegant black
+++ Total absolute single-handed fit
+++ Roller receiving wide enough for wider tape (up to 2 cm)
+++ Robust, hardly prone, super durable

Cons:
--- Might (if it is very strictly speaking) still be a little heavier

My Conclusion:
I was quite surprised when I saw here the streaky reviews. I have a model home and one in the office. Both fulfill its purpose perfectly - I have always been completely satisfied.
I would advise everyone to this model - at least if you want a stationary device. Please zoom back in work bag there is naturally less suitable.
