Feser One - NO-UV, PURE Red- Non Conductive Coolant 1000mL 4260119640412

Looks great in my system. Very easy to install into the reservoir with the included cap. Had Mayhems Aurora coolant before this and prefer this more. My temps have dropped a few degrees. I assume it due to all the extra stuff that was in the Mayhems.

Everything is good about this product, my problem is, it is overpriced.
