K100 fuel treatment

[Indiana79]

Has anyone tried k100 fuel treatment/ stabilizer. There are a lot of good reviews on amazon and I watched a few youtube videos on it. It's a product similar to stabil or startron. Just looking for feedback I'm always looking for the best stabilizer for all my classics and small engines that sit frequently.

I never used it but I started up my mower a few days ago after having stabil brand stabilizer in it and it started on the first pull. I followed the instructions and added a bit extra at the end.
