Didn’t protect during lightning in Miami. I had a close lightning strike a year ago & bought this hoping it would help. Bought in August , had a strike 2 days ago & once again att router & desktop nic card burned out!!! I now have to troubleshoot (so time wasted ) & hope it’s just the nic card which I also have to replace. I’m going to try to submit a claim to belkin ... forget that it’s almost impossible to figure out how to submit a claim. I guess I’ll need to buy something more substantial to replace this useless device.
