Bought a pack of 2 Taiyo 3-Pin Plug Adapters from Challenger at Funan for S$14.90 (after 10% member’s discount is S$13.41). I like it because it has individual switch to control power to each of the 3 3-pin sockets.
I find it weird that some countries do not have the concept of switching off an individual switch on a power strip but rather leaving all the switches always on, if you look at Belkin Surge Protectors, there is no on/off switch available.
