Excellent, but...
Let's face it, Corsair is not a low-cost brand, but this is justified by the quality of their products and the packaging that goes with it. Here, you have a pump + tank combo with impeccable finishes, which delivers good performance, and if you associate it with a Commander Pro, you will have an automated management of the pump rotation speed according to the needs, via a temperature sensor supplied with the XD5. And then, the iCue, it gives nice effects if you have a case with glass panels.
The only noteworthy point is that the documentation provided may seem unclear, if in doubt, refer to a YT video on Corsair's channel, in which they illustrate the installation. Also, if like me, you want your XD5 to be screwed directly to the case chassis from the underside of its bracket, make sure you have the right size holes in the right places! I had a bit of a scare about this when I installed the pump in my Tower 900 on one of the two front housing slots (as you can see in the tower photos where you have a nice pump proudly displayed), and I finally got away with screwing the XD5 onto its supplied 120mm bracket, and dropping the whole thing without screwing it into the case. It's stable, it's just about 1 or 2 mm off, so I was lucky, but beware.
Otherwise, excellent product that I highly recommend!
