But hey - follow the hype!

I'm not sure why you're so defensive. I've already said that if we have some verified reviews/reports, it should be recommended, which it sounds like it is.

I'm also not sure why you think one product working on one car automatically means it works and works well for every other car? This is pretty obvious stuff.
