Query: Poor design

I call this a frisbee switch because after six months of trying to get it to work properly I threw it out of the window. I took it to the shop and took it apart to see why it wouldn't work. It has an uncorrectable design flaw. It works by simply moving an internal optical cable from one port to the next. Simple enough. The problem is the gap between the ends of the cables it too large. The cables have to be lined up perfectly for it to work. The sockets on the switch fit so loosely it is not possible to maintain proper alignment and the signal cuts in and out. Don't waste your money.
