Performs as claimed by manufacturer!

I bought a few of these on a whim to test them out. They seem to perform as well as the manufacturer says.
We were having some storms last night, and I got a call from a customer that he had no WiFi. In this particular install, this surge protector was installed between a PoE injector and an EdgeRouter X. There were no lights on the ERX, so I replaced the surge protector and, Tada! His network was back up within a minute or two of my arrival on-site. The cable modem at this location was toasted by a lightning event, so he'll still have to wait for his ISP to come replace that before he has internet again. I generally advise clients to purchase their own modem, but at this location there are frequent lightning events, so it's actually more economical for him to lease the cable modem from them, and let them deal with replacing it two to three times a year when it gets knocked out by lightning. The lightning events at this location typically effect only the cable modem and whatever is directly connected to it, which tells me the offending current is coming into the house through the coaxial cable connection. Apparently, the ISP's not concerned enough to install adequate lightning protection on their equipment.
