It is as simple and easy as the description says.
I have three of those in my studio and I haven't had any problems for two years.
Pros:
All the cables are already marked with numbers, divided into three colors, so very easy to use out of the box. Since I'm using three of those, the I needed to do extra marking for channels, but not really a problem of this product.
REAN connectors are durable, no problems so far.
Cons:
The ONLY thing that could be noted as a slightly negative for some, is that they are not exactly the same length. I have three, and they vary in lenght about +/-40cm. Not a problem for me, but could be a problem for some people.
