bought this whilst it was on sale and does not disappoint. Get it on sale whilst you can for sure.
this is a good lube for sure. For 3x3s I recommend about 2 drops of reagent A, before breaking it in with a solve or two. then, add 3-4 drops of reagent B for a smooth, controllable but fast feel. for more control, use more reagent A but for more speed use more reagent B (this is better for big cubes).
Only complaint otherwise would be when not on sale, it is a bit pricey and I'm not sure whether id pay that for it. As I say, catch it on sale before it's gone.
