Does anyone else have the problem that the screw heads are very easy to break? I have already bought some of the modules and only got this problem with the modules I bought recently. I have overtightened every single head of the screws. This has not happened to me with any of the older ones. It seems to me that the manufacturer is saving on the screws and is now using softer steel. Of course, it's possible that I got two assembly products at the same time, but in any case I'm pretty annoyed now. It is no longer possible to take them apart and screw them together again.
