Tapo Smart Wi-Fi Wall Outlet Extender review: Flaw ahead!

Don't buy this multi-outlet for its surge protection feature, as it won't warn you when it can no longer deliver it. TP-Link's Tapo Smart Wi-Fi Wall Outlet Extender has some great features, as well as one critical shortcoming that prevents us from recommending it. Tapo doesn't make big promises for this product in terms of its surge protection, but it does list a key feature on the box: the ability to warn you when it can no longer provide surge protection. The Tapo Smart Wi-Fi Wall Outlet Extender isn't all bad news--provided you're not buying it for surge protection. Most surge protectors use sacrificial MOVs (metal oxide varistors) to absorb excess voltage from power surges, and this one is no exception.
