Not all banana

I have a really good investment, it is not high end, but so close as I can finance it. Because something is the worst part, or falls, I naturally appropriate cable - 4 sq mm - and of course it should be banana plugs.

Now they are here declared "to 4qmm" suitable. O. k., The word 'appropriate' is not there, would have really exaggerated.
One has trouble squeeze in the cable, and then it is hardly possible to sink the screws yet so far that the red or black cover can be screwed on it again.
It may be that one at 2.5 cables these difficulties he has not. However, banana plugs for 2.5-er cable anyway pearls before swine. Whose plant banana plug is value which should not take so mediocre cable.

In any case I again bought myself another plug.
