I'm not sure why there are bad reviews. This seems to be the real one, the quality is very high, it's strong, works perfectly on my new car, it doesn't leave residues. It's great, I don't need to wash my car as often. I just don't scrub my car with it, I lightly do a pass to remove the dust and it leaves my car shiny even if it doesn't remove actual stains. My car does look way better than when I don't use it.
