doesn't give battery effect because its anodized.

You people can't read ?

It's copper & copper ...

I think they are misled because of the copper - anodized copper ;)

Internals

thnx to Dieter !

thanks for sharing the link :super:

looks simple yet affective, wonder if performance can be increased even further if the block would be engineered following some guidelines of the TDX design, meaning that a small nozzle is placed above the copper cutouts to direct the waterflow

nehh, it's not possible for him to make blocks that are much more complicated

LOL, it's not that hard to make.
It's only drilling and tapping once more, and making an extra fitting. This would improve performance a lot. (as I said in the topic @Xtreme-oc)

if he can design the block that it still only requires "just" 2 fittings that would make it a big PLUS, when it comes down to easiness of use.

in my humble opinion, to say it short and simple:

The internal design sucks.

straight fittings you mean?

agree
