Отзыв о Класс SC 20 с выдержкой времени QSU от Manny Darawi

This product is not worth buying for any industrial and scientific purpose .It did not even last a week before it stopped working properly. The only advantage was that it helped safeguard the machinery from possible circuit malfunctions. However, this benefit became irrelevant due to its unreliable mechanism, leading to a frustrating waste of money..
