I used to use it because they reckon it's 'self cleaning', which are magic words that stimulate the lazy parts of our brains.
It's OK, but you have to keep applying it, so it's bad value for money - and it's expensive anyway. I think it's designed for machinery that needs maximal uptime, but you must keep applying it if it's going to work.
I just use normal thick stuff like finish line wet lube and wash the chain occasionally.
