Worst lawn seed, I had ever :-(

This is the worst lawn seed, I've ever had. At first it was still, he has germinated and also looked really good, but the joy was unfortunately short-lived, after half a year, most stalks were dead and there was left only a meager remainder. A dense lawn I could not achieve. Since each cheap seed is even better from the supermarket or hardware store, both I have already tried and never achieved such a miserable result. Never again this "miracle grass", shame about the money and the work.
