This rack is very sturdy, with built in power supply which is shielded. I think they did a good job here as it is very quiet with my modules. What I really like is the link function so I have begun to build kind of channel strips (perhaps more like complimentary modules than a traditional channel strip) of 3 modules each, then the last 2 are the stereo compressor. The link function in the rack means less cables and less channels required of your interface :)
I think this is a nice option to get a reliable rack at an affordable cost, and with the all important link feature.
