Beautiful part, but does not keep all its promises.

I work professionally with the occasional Stripax and have now privately ordered the Knipex.
Important to me was a good stripping with small diameters.
For larger diameters both work equally well.
The Knipex operates "smoother" and more smoothly, so there is not such a jerk.
Even with the Knipex can not fully deduct the insulating material so that your splicing of wires is prevented.
Just this purpose, the cable end slide 2-3 mm into the gap of the limit stop.

For smaller diameters, the insulating material becomes more important as the diameter!
The Stripax comes here with softer materials clear how silicone-like insulating materials.
However, one must here strive to fine-tune, which is missing the Knipex.
The Knipex therefore does not always provide the promised minimum diameter!

So why only 3 stars?
I bought many years ago a cheap soldering iron, of a suitcase, consumables, and a stripper contained next to the soldering iron.
This case was about. 8 The enclosed pliers Knipex the stripping result in equal!
I have unfortunately found again only after the purchase.

Price-performance therefore deficient.
