This product, a relatively sophisticated surge protector, is easy to integrated into an electronic system, which is exactly what I did. It is highly rated to protect numerous electronic devices against strong power surges that can seriously damage the equipment. Such surges may actually never occur. But if one does, it will typically occur during a thunderstorm. The desired and expected function of the protector is preventing serious damage to electronic equipment, such as, a TV set and/or a DVD player, by absorbing the surge of electricity before it can damage the equipment. The downside, of course, is that one does not really know whether one's equipment will, in fact, be protected from such serious damage until an actual power surge occurs. Obviously, that surge will be the critical moment, and there is no way of predicting when or if it will occur. Indeed, as I said, it may never occur. Therefore, the device, the surge protector I purchased and installed, is simply a de facto insurance policy against possible damage to my very expensive electronic equipment. Buying this product is akin to purchasing and installing a smoke detector, buying a fire extinguisher, or putting on your seat belt. Obviously, this makes a review of the product, before the occurrence of a power surge, rather difficult to write and actually be helpful to other consumers. I could say that if there is a surge, and the protector prevents damage to my electronics, I will give it five stars. On the other hand, if there is a surge and my equipment is still destroyed, I will give the protector the fewest possible stars. That being said, I can honestly tell you that I sleep better knowing I have this surge protector integrated into my equipment. I suppose that is what we call "peace of mind". Not using a good surge protector is, in my opinion, irresponsible.
