hi bought "NEW" Smart plugs over the internet and set some set Great but have 1 that does not work right out of box. After talking with your tech support on the phone and online have decided my smart home product choices going with the tp-brand has been a very poor choice, Not only was they unable to resolve my technical issue they were not interested in backing your product with warranty information. Had to dig deep into finding how to regerester my product to see if it was covered by warranty. To my Big Surprize the smart plugs i Bought "NEW" still in boxes and still wrapped from factory are out of warranty and not covered I guess Its amazing to be how they can go bad sitting on a self Maybe you neeed to put a sell by date on your product. When i do my reveiw on socail media "You tube, Face Book" Ill be sure to mention that detail so others can check out when product was made so the can see if warranty is still good. All this over a $15 plug..... Now my Issue is now the smart switches that i purchased at same time from Amazon with not let me regester them does not reconize S/N number... I know big shocker to me too have problems with the switches to....
