I got it for the Lial Li SL-INF fans, TL-LCD, and the Galahad II Trinity 360 SL-INF cooler. I installed everything and they work great. It has a good magnet on the back and it's convenient to attach it to the case.

It solved the problem I had with the motherboard and its one USB 2.0 port. Simply connect it to a USB 2.0 port on the motherboard and it gives you five! I have connected my liquid cooling, 2 sets of 3-pin fans, and a 24-pin RGB streamer cable to it. In total, 4 USB 2.0 ports are being used and they all work perfectly!

It does exactly what it's supposed to do without causing any problems. Whoever needs more internal USB 2.0 headers, this might be the best solution

Very convenient, when your PC has internal requirements for multiple USB slots (commander pro, 2 nodes, water cooling, etc.)
Beautiful, small with all the necessary cables, and adhesive to be discreetly placed on the back of the case.

Personally, it did not satisfy me enough.
My motherboard has 2 USB ports.
I bought a PCI wifi antenna with Bluetooth and I needed one more slot, so I bought it.
I connected it to the motherboard and placed everything on top of it.
The NZXT fan controller does not work on it and is not recognized by NZXT CAM, and the PCI wifi does not detect the Bluetooth
(Although it detects it when connected to the motherboard.)

Nice build quality.
Overall, I was disappointed as it is slightly useless.

It serves its purpose as expected, in combination with the build quality that you find in NZXT products.
