I recently ordered a Yongnu OC-E3 ettl cord from the other side of the world because it's so much cheaper than Canon. After some time having it on a flash bracket the metal base plate on top of the adapter where the real flash goes started to wobble, and recently it came completely off - the metal screws with the hotshoe were torn out of the plastic plate.
This doesn't come as a complete surprise since having a heavy 600rt flash mounted in an angle and walking around with this puts quite a torque on the base plate of the ettl cord...
... My question is: Is the Canon original any better, or are there sturdier 3rd party oc-e3 ettl cords? The Yongnu otherwise is fine, but the metal screws into plastic is just cheap and cannot take any strain at all (at least my copy).
Edit: Added pictures with torn off base plate
