I got the 1-3 and the 1-2 versions of this for my radio setup am happy with them so far. Build quality seems good. I can't see how things are connected inside the molded center piece but it does make for a cleaner setup than my DIY versions.

This is pretty heavy duty and works great.

Appears to be actual 10 gauge wire.

Just had to slide down the sheathing for the red and black blocks, then slide them apart (they are dovetailed together) rotate the red and black blocks and then use different sides of the blocks to dovetail back together. I'm making it sound a lot harder than it actually was. Wish they made a version where there are four Anderson HPP plugs in parallel to one Anderson HPP plug.
