Are you sure it isn't an official product?
if this question is directed at me then. i'm pretty sure, since (1) i got this from china, (2) cheap and (3) the seller admitted it is a clone. as i dont have any "hardground" toolchain and project yet, so this unit is still "untested" other than detection test by segger jlink uploader SW iirc months ago.
i'll be glad olsenn if you can make teardown of you original jlink-edu and post pictures here or somewhere else as you like.
