But here comes the first 'only ...' - The stakes are probably forged, a quite suitable method. But: The flange between actual tongs and the inserts is there, albeit in a small area, rather randomly. If we add the tolerance of conventional mass commodity crimp contacts, you quickly in areas where the gun closes too far or not far enough, which in doubt can lead to an excessively loose connection or for squeezing the wires - both for using electronic devices a risk and the layman neither recognizable nor correctable. If it is the worst case for liability and risk of consequential loss, threatens lamentation.
And here comes the second 'only ...' Although everything is pretty neat, almost lovingly, packed in a sturdy bag, but what completely missing is a manual. Do not laugh, when crimping can be done just about everything wrong, what is thinkable and unthinkable. The color gekennzeicheten standard car-crusher may also be the most inexperienced layman still classify and hopefully use it correctly. But what kind of crimps the remaining 4 missions are good, you can only guess. There are dozens of manufacturers norms that usually only function properly if the correct tool is used. A "basst scho" is not there.
When I asked the seller on this subject, although I got immediately a very friendly reply, but except for a picture of the parts list that had nothing. The stakes are as indeed provided with numeric codes, but what the mean - no evidence.
I can the seller just strongly recommend to procure the complete operating instructions to translate into understandable German, and to allow all current and new customers to come - the European product liability law is relentless - and upheld on anyone who shows up in the distribution channel, to the personal assets.
With a few minor improvements, the requirement for five stars would exist, so unfortunately I a less. A TÜV-professional would probably have judged harder ...
