Review on DIYhz Aluminum Computer Graphics Endothermic Industrial Electrical and Thermal Management Products by Jason Mitts

You get what you pay for. I ordered a set of 4 six months ago. In one of them, 5 months and 3 weeks after commissioning, leaks appeared around each connector. The circuit was run with a standard high temperature coolant with safe aluminium/copper corrosion inhibitors. They're not terrible, but you have to check them out. every few months for leaks.
