$8 for a 7oz can is cheap enough to give it a try...
...but the other hand, the fact that it's so cheap for such a large amount leads me to assume (as a pessimist) that it probably doesn't last very long, and you'll be sheep oiling your chain before every ride. That would be a dealbreaker for me, as I just keep trying new products to find the one that lasts the longest between applications.
But I am also very curious as to see how this one works. Someone else buy it do I don't have to. My bottle of Muc Off Hydrophobic Team Sky edition is like 80% full (and goes 500 miles between applications,) so I'm not going to need chain lube for a long while.
