“Its good. The good is that you clean and lube you chain in one go. Shake the bottle and apply it to both insides of the chain and wipe off the excess -- the rage is certainly dirty so the dirt is coming off. It is a bit difficult getting the lubricant on the side of the chain where the movement is as the end of the bottle is convex. If it was concave it would site on the right place of the chain and not slip off. Its also difficult to get an appropriate amount to come out - not too much as its a waste, not too little as then there is not lubrication or cleaning!”
