In addition to this Stripper in red can be found on Amazon from the same injection mold at least one device in dark red and one in blue - further, I have not wanted. All three devices are certainly offered by the same dealers - of course vary. So I ordered the red variation, but get the dark red.

The black slider (the yellow blue copy) that you see in the product picture, you open the wire stripper. Then wrap the cord, connect the wire stripper and can lock the slide again, if you want. Now turn - cautious as always - the Stripper, until the insulation is severed. Extra pressure you can still carry on the thickened ends the Abisolierers. That makes almost fun.

If you have only 5 cm free cable to install an F connector, you will appreciate the advantage of this Abisolierers. As long as the cable is not yet installed, a utility knife is also not bad.

The "blue" Product description says something about "practical marks for cutting length". This means that probably the two webs meant in addition to knives. But they are only of limited help, since they are not very marked. Here is considerable room for improvement, as well as a simple means I expected.

Conclusion:
quite a useful part of the casual installer - Professionals need better. Two star deduction is available for the half-baked design and the comparatively high price. Which is still in the order that he plays no significant role in a satellite installation.
