Customer Review

Reviewed in the United States on July 24, 2014
It seems to work just as well as the one originally provided by my internet provider. Maybe even better. The original one is designed with varistors, which can overheat and explode during lightning attacks. This one is designed with spark gap tubes, which are less likely to explode. Varistors have other advantages, and spark tubes have other disadvantages, but for this application, I like spark tubes better.

Several lightning storms later, it is still going strong, which I cannot say for the last varistor version. But then, the effects of lightning are rather unpredictable, so it may just be random chance.
