Title says it all. I have a number of P100s which are about a year old. Some of them seem to work fine but the power is not actually switched off when it is supposed to be. Almost certainly a hardware problem, not firmware. There are many comments like this in the TP Link community and on the wider internet. Are TP Link going to do anything about it, or do they just expect us to buy new plugs and hope they will work for longer than the old ones? Not me!
