Good lube, but better ones out there
This stuff is great if you have your chain perfectly clean and dry. That is practical if you clean your bike once every month or so. Since I am washing my bike a few times per week, I rarely get the chain looking like new or take the time to completely dry the chain before applying lube.
If you apply this lube to a wet or dirty chain, it gets nasty and black really fast. It also smells a lot stronger than other lubes and is not fun to get on your fingers.
