Used to wax my chain but have shifted to this for convenience since I maintain a few bicycles.
10/10 ease of use and performance. It does everything they say, my drivetrain has never been happier. Cant speak to the longevity yet since this is my first use but it does make the drivetrain feel buttery smooth on road. The pedals give an almost melt forward feeling when doing hard sprints and acceleration drills on a track which is something cool I have never experienced with other lubes.
10/10 shipping experience. They shipped each bottle in its own cardboard with foam inside to prevent damage to the applicator which was a super pleasant surprise. They shipped from USA all the way to Asia in 3 days which is faster than most of my Asia to Asia shipping experiences.
Will be using this exclusively from now on. Their quality has me interested in their other stuff now too.
