Well I didn't find any real bad reviews about the kit other than people mixing in pastel coolants from mayhem which reacts with the nickel in thermaltakes parts. If my thermaltake aio lasted for a year and a half I think the kit can.
also the internet seems to just hate everything. Every damn PSU for example is bad and only the all mighty seasonic should be bought... Same with waterblocks, only EK is allowed to be bought, while I've seen EK fittings leek with pros lime Jay from Jayztwocents
Besides I'm really impatient when I feel like trying out stuff. I bought a surfboard and learned how to do it in one day after I learned they existed in Lebanon, for example.
Now I've been running it for a week, after I leak tested ofc. The temps are great, the waterlevel is still the same( marked with a marker on the reservoir). And the coolant still holds its color.
