After 6 months that I have it, I can say that it's worth its money. I have it to power a laser welder and it has saved me from many fluctuations.

Flawless product! It filters even the slightest fluctuations in voltage when the home network is loaded!!! It intervenes and corrects without any problem. Just pay attention to the following: The stabilizer has a power output (output) with a schuko socket and two poles, a positive and a negative one. For power input (input) it does not have an integrated cable, only two other poles, a positive and a negative one (5 in total along with grounding). Which means that you will have to do some handy work, that is, cut the end of a power supply cable and connect the three cables to the corresponding poles of the stabilizer.
