I bought this to replace a surge suppressor I had for over 20 years. The old one didn't have a light and I didn't know if it was still working. And since it was protecting an expensive espresso machine I figured the cost was well worth it. LED light for both "Protected" and "Grounded" give peace of mind. Being LED the lights should operate for quite a long time. 6 Outlets come in real handy for a kitchen counter too.
