    works
    I used this to protect network from another building maintained 1000Mbs conductivity between switches. I hope I will never find out if it really works or not. Seems well built metal RJ45 connectors and sturdy plastic box with weather sealing although mine is indoors.

    Spark tubes instead of varistors
    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.

    This is an excellent unit.
    This is an excellent unit. - But do make sure you are using them with shielded cable.

    We have some underground lines between buildings and are using these to replace another companies units which we have had historical issues with.

    Basically, our previous units would burn out when there was a lightning activity anywhere remotely near us, these seem to not be bothered as much by that while still providing good protection.

    All of these surge protectors really need shielded cable though, so keep that in mind.

    Excellent
    This unit does not restrict any traffic flow. The only downside is that you have to crimp in your own grounding line.

    Gigabit!
    What I thought to be an issue with the device was actually a problem with the patch cables. I had to order a network cable tester to figure that out. The culprit cables are repaired now and the device functions as it should.

    It does great at what it is ment to do. However, i dont believe that it will throughput gigabit. My gigabit switch believes it is connected to a 100 megabit source. The source is from my gigabit router and this is the only break in that connection. I will try a different gigabit surge solution and report back
