Sorry if this is a topic already discussed but I didn't see it during my search.

I am a first time nscale modeler and I have designed my first layout and about to start the benchwork.  But I went through my plans again one more time and also looked at a few youtube videos and I noticed that there are a lot of videos on how to fix the Kato  #4 turnouts.  I'm using #4 turnouts on a small yard as part of my plan.  They use up less space, but now I'm worried there might be some problem with these turnouts.  I've noticed these posts are ten years old or older. 

So here's the question.

Are there still problems with these Kato #4 turnouts?  I know that track geometry is important but that's not my concern.  It seemed to me that there was a problem with the manufacturing of these #4 turnouts.  For those of you who have recently used these turnouts, in your opinion has Kato resolved those manufacturing issues?

Much thanks
