Used it on my H200e to externally connect a 4 in 3 hot swap case to my PC case. Works exactly as expected - all four drives are seen/recognized by the operating system with no issues. I'll be ordering a second one soon.
Pros
It has an external 26-pin Mini Sass Soff 8088 connector (with release ring) on one end and 4x 7-pin SATA connectors on the other end.
