FZ Calm + Rush Speed Cube Lubricant - Rubic Cube Lube for Controlled & Extra Speed - Set of 2-10cc

Hands down the best lube combo for speed cubing. If you’re on a budget I recommend just get calm. If you can afford both, go for it. The work together flawlessly and the feel of the cube is fantastic. It makes the layers glide smoothly but without loss of tactility or the addition of unwanted gumminess. Calm lasts a good while rush lasts about a week maybe. Be aware, calm has no water in it, rush has some. I use both on my smart cube but just know that’s a risk. I put rush in my smart cube not knowing it had water in it. I had no issues and just decided to continue using it. Nonetheless you shouldn’t put lubes with water in smart cubes. I have mystic, angstrom gravitas, angstrom dignitas, weight 5, fz rush and calm, dnm37, and by far if I could keep on it would be calm. It’s the safest bet on any cube, and the most versatile.

But looks very good

My son loves them so much. His cubes are super smooth and controllable now.

BLUF: I recommend. My son uses this for his 10 cubes. He said it does the job without being extremely messy. He would purchase the set again. Bottomline: I recommend.

Not worth 30 bux but amazing lubes!
