Nothing is perfect, but I like this one.
It is true there are some drawbacks, like the Powercons and XLR on the sides but it is useful if you place several bars in a row.
Then you can easily daisy-chain the bars with very short cables, so I think you should not use them as side bars because you want the cables in the center then.
Also it is right that the 35mm adapter is not roadie-proof ;) But hey, that is easy to fix.
The fifth connection is great to add some special FX or whatever.
Powercons are not Neutrik but feels good enough.
The general finish is fine but the total length of the bar is a little on the short side with 120cm.
So, for this money, and you have a good purpose for it I think they're great.
