very cheap products, but low quality

The set is very inexpensive, the tools work largely. The tester can be with me but do not turn off. I have against the supplier but not complained, the effort is simply not justified. The pliers work well, the testers are a nice addition, but only in principle check for continuity and possible bridges. Most can be done with it. For Professional Use the set is rather nix, perfectly adequate for occasional use.
