I like them (4ms row power) a lot. I have a fairly large setup and I ended up with 4 of them. Two on one power brick and two on another. I spent tonight, fittingly, making new jumper cables to match the twos's together (the old cables were about 20cm long and just got in the way. Cables getting in the way is a good thing with patch but not with power. The new ones are 8cm and much nicer.
Yes, 4 is probably overkill but my original setup was 4 boxes, bring-what-you-want-to-the-party whereas my new setup is static (it fills an old school drafting table's storage area).
If I was doing it again, tbh, I'd probably do the same thing. I like being able to select power on groups that I use together, and was willing to pay the $$.
