1.0 out of 5 stars Fried ether net ports after storms, suppressor unharmed.
By Trump Won By A LOT on July 13, 2019
This is the kind of device that is difficult validate whether it works as advertised. And, given how much power is in a lightning strike or transient, it's unfair to fault them if they ultimately fail to protect your equipment. That said, I'm giving this a 1-star because what I've experienced leaves me discouraged and shattered any sense of protection I may have had..

About 10 days ago, we had a close lightning strike near my home. I don't know where the strike actually hit, but the damage was significant enough for me to look for protection. I lost several IP cameras, multiple PoE and PoE+ switches, and a 500' run of direct-burial, gel-filled, unshielded Cat5e (see photo). This happened BEFORE I installed the Ubiquity protectors.

I have three main switch locations. The home, the barn, and at my gate. All three are tied together by approximately 500' of buried cat5e cable. When lightning struck on the street, the transient traveled down to the barn, and then to the house, frying many network devices along the way. So, I figured installing these Ubiquity surge protectors at each end of the 500' runs would contain the damage to one area. Incidentally, there was no other electrical damage to any non-networked devices in the home.

Tonight we had a rather severe lightning storm. While we didn't observe any close strikes, the switch at the gate and the switch at the barn both failed on the ports to which the 500' cable between them was connected. Neither of the Ubiquity suppressors at the ends failed. They both still allow full data transmission. Both were grounded within 20" of the ports.

Fortunately only the individual ports on both switches failed. That is better than losing the switch - or other devices attached to it. I don't know if the Ubiquity actually prevented more significant damage, or if what I experienced would have happened even without the suppressors.

I was really hoping that these things would act as fuses - opening the circuit - protecting downstream equipment, and making it abundantly clear that they worked as intended. I have no such confidence, and really think either a) these are snake oil offering a false sense of security, or b) I am expecting too much from a $12 device.

1.0 out of 5 stars Failed to prevent thousands in damage due to poor design
By BillP on August 31, 2021
The mast full of equipment was hit by lightning. This failed to prevent the surge from entering the house and frying thousands of dollars worth of equipment. And you can see why, it's a bad design. The PCB traces are too small and blow, disconnecting the surge arrestors from the ethernet lines.
