The extension board looks nice and compact with USB power points - but it has a major flaw. It has a 2-pin plug although the 2 sockets are 3-pin type. That means the board has no connection to mains ground and is unsafe. However the picture shows a 3-pin design - which is very misleading. Also the seller has no return option - so I was unable to return the item, although the picture is clearly not what the item actually is.
