It looks great in clear tubes. It's a bit of a pain to dry if you spill some - you really need to wipe it, but otherwise it's good liquid

Top quality

It's a conduit what is there to say

Is good like the original

I really like the way the lighting in the pumps refracts through the clear coolant.The photo is just after filling so there is still bubbles in the liquid, even with the bubbles that iridescent type glow is really nice.I hadn’t sealed to move the pumps after taking the photo so had to drain, then refill, the system. During the refilling I had sealed of one of the fill ports properly.I got soaked in coolant. 2 days on, and 3 showers, later I can still smell, and feel, the coolant on me. Not an unpleasant smell; just a lingering smell.
