The product does what you'd expect and the quality and finish are good, but it has two major shortcomings in my opinion.
The first and biggest is the fact that the sockets are angled. This is not a problem if you are plugging cables, but try to plug several bulkier wart power supplies and you have a problem: they don't fit! This way you end up being able to use just 3 out of 6 sockets. I really can't think of any good reason why they couldn't just use straight sockets. I intend to buy a the t.racks Power 8 S straight (Thomann item number 427859) which has straight sockets, and swap them out. The second thing is the main cable which comes out of the side instead of the back. Depending on your rack, you may find it doesn't fit comfortably and you'll need to awkwardly bend the cable to get it to go in.
All that said, based on reviews here are no better alternatives, so overall this is still a relatively good product.
