after a grilled internet box and an amp after a power surge, I deleted all the classic Multitake my apartment and replaced by this model. I appreciate the robustness and the assurance provided by the manufacturer (the level of insurance depends on the model purchased). Missing from my review the testing of this device in real conditions (storms, large surges), but for now - although I do not know if there is a link between the two phenomena - untimely extinction my electrical devices that occurred during use longer appear at all.
