will it only work once?

Really depends on if you take a direct hit. Then it will probably fail. Normally this device will handle multiple surges before failure. How many depends on severity.

I unfortunately purchased this unit and after one surge - that was it. Total waste of your good money

Yes. But if the green light is still on after several nearby lightning strikes as in my case, it will continue to protect. If the green light goes out, you will need to replace the unit; being glad that it saved you from possibly thousands of dollars in damage! This is the case for ALL surge protector devices.

As long as the green LED is lit your good. It all comes down to what kind of strike it's hit with. Most normal surges on in coming power should be ok. Lighting on the other hand can be a lot of heat, which would be the problem. That's why as long as the LED stays green it's good or turns red it's been exposed to high heat. It has a 3yr warranty and comes highly recommended. For most people it's cheap insurance. They pay up to $7500 I believe if something happens during the 3 yrs. I know people who have had them 10 years and still working. Hope this helps.

Also wanted to note that this is for incoming power problems only. You should also use surge protection at each electronic component, like an outlet or strip with surge protection. Internal surges can happen beyond your power source, example: Frig on same circuit, as a vacuum is turned on, can cause an internal surge on this circuit or one near it. This is a better setup for having all round protection. Most people I know have one or the other, better to have both.

It will only work "once" if the "once" is severe. Before I had one installed, I lost a control unit on a power vent and a motion sensor due to "dirty" power. It has been 9 years since I first installed it and it still glows green indicating it is working. The control unit and other direct wired electronics have also functioned fine. Our power (in rural area) goes out quite often (almost weekly) so it has paid for itself many time over I'm guessing. I also have a home generator and it seems to dampen the surges that occurs when we need to switch to the generator as well. It will only work "once" if the "once" is severe.

just once. there are several types of test in the box but they're each designed to only be used once.

I cant really answer the question because it only worked 1 time and then quit working.

No, it would have to be re-programmed each time, or do it manually but that defeats the purpose of this working automatically.

It should work right away, I think it's broken. Need to return it. I had to return the first one that I bought and had it within a few days.

no, but I did notice this product only worked 1 time and lost its effect, would not recomend

yes, you can use it multiple times, you just have to recharge it after use. Hope this helps. :)

Don't think so. Two suggestions:1. Try to reset2. Make sure you did not produce a loop

I did. I got it to work once but then couldn't get it to again. Ended up returning it.

I have one and have only used it a few times ... Without problem ... But this weekend I will try some more to see if I get your problem

It should, what you have to do is turn it off then turn it back on again after you plug it in should work.

The answer to the question is yes. You are a lucky one, I order this item twice. The first one Worked reasonably well, bit vol adi was defective. Second time I got it only receive static and The reset button was defective. Goog luck!!!

For me, it only worked the first day. After that it never worked again. Not sure version I was running.

Cynthia, in theory the answer is yes but, my machine worked only three times before breaking. I'm not a good person to recommend this product.
