After a lightning sent my wireless router to the afterlife, I decided to purchase a power strip with surge protection. The delivery was super punctual, as predicted. The price is OK, provided the next flash keeps the surge, what it promises. I can not assess at present but. Small drawback: I can not remember power strips that had on the bottom recesses for bolt heads. So you could see the power socket on the wall, a shelf or similar fasten. Unfortunately, these recesses are missing in internal chair. Too Bad.
