I wouldn't not try out blackfire because of this review......just like I would not jump and go out and buy it because of one GREAT review. I think it is still too early to tell, but what I would do is remember all these reviews and after about 10 more or so, evaluate the systems strengths and weaknesses.
It's tough releasing a new product, because you are never going to mimick every car color, and application method, situation, temperature,etc,etc,etc.....to work out the bugs. Plus there is always the idiot factor in all of us to some degree. You can see how one bad review effects the reputation of a new product for some people. Perhaps this is why SAL is testing ZFX to DEATH before release to get it perfect.........
