I got this as I was curious to see how well it worked, and liked the idea of the brush applicator. It does take quite a few turns to get the lube out the first time, but after that you only need one or two turns. It works really well in all the cubes I tried - gan 14 pro, gan 12 maglev, rs3m 2020, the worlds smallest cube lol. It’s a really fast lube, and adds a nice smooth soft feeling as well!
