So also with me. After 4 months all disengageable sockets have given up the ghost, and no power supply more. It can be switched on either by the wireless switch or by the switch on the power strip. Conversions do not really interest me, I run but only a danger that the same error occurs in 4 months.
If you are lucky and get a more durable bar, you have a perfectly usable product. The wireless switch is very convenient when the bar is not easily accessible. Unfortunately it does not always move up a first time. The sockets are pleasantly wide apart. The problem is that large connector cover other outlets have been so much less.
