I still would have to buy the first Meike crap. But thanks fpr testing and confirming my prejudice. At this prices I do expect what you described. Friction for the coupling - the next thing possibly happening is that the camera itself gets damaged. Pas "bon marché".

 

  I have now two of the three which still function..........I know not for how long!

 

    I will wait and find a set of Kenko tubes.
