I decided to invest in TP-Link as my choice of smartphone, however I believe I have made a mistake, I have now had 2 x P100 and 1 x P110 fail on me, from different outlets with hardly any load, they are online, the light goes from amber to green and vice versa, your hear a tick but not the louder actual switch and nothing happens, sadly they are all out of Warranty and when I raised a complaint they weren't interested, so all I can say is be warned, these plugs are cheap nasty and made to last, due to there lack of support/help I will now be swapping out to a different manufacturer and using them for any further investment.
