The only time I did have issues was when I removed them in different positions such as in the winding position for example and it was because I was working on two different things at once having forgotten to pull stem out in winding position. As for the clones it makes no difference as they might as well be made of kitchen foil as I steer away from them ( also my opinion!)!
