Received some hilink transformers today from QIMEI Electronics Network Technology Co., Ltd in China; Compared to the posts above, the 3.3v ones look genuine, but not sure about the 5v ones.
The side the pins come out of does not have the central hole and feels 'squigy' so I lifted it off one of them and the space inside is not completely filled with the encapsulation stuff, but it does feel slightly rubbery like the real ones...
Maybe a new variant of the real thing? Or fake?
These are destined for being outside in waterproof boxes, so I'll let you know if any catch fire....
