As a generator, it works but it's not the best. In fact, the simple generator from the same company is MUCH better. Now, as a LAN tester, no, it's not good. Maybe it works for use in household environments with short cables, but for professional use, NOT AT ALL! (for simple use without checking length, losses, etc., the cheap testers for 5-10 euros with the small functions work perfectly, so it falls behind there) Overall, unfortunately, it is a very mediocre to bad tool that, if a combination of a cheap generator and another LAN tester surpass it, then it has no reason to exist, not even for simple amateur use (for professional use, forget it completely, it will just expose you)

Black garbage like a generator plays so when it smokes like a networking device it does its own sometimes.... I didn't even bother to return it... Sometimes when you want to do your job properly and effortlessly you have to take a serious tool once in your life....

It is very good! But for an office where there is no noise. The problem is that it doesn't sound loud, for example, at work I wouldn't prefer it for this reason alone
