I can not understand the rave reviews. Neither the "Test Winner", which to me, Stiftung Warentest has always appeared very suspicious. It may be because maybe that the test is almost 10 years old and the recipe was changed. Z. Zt. Which means less cleans and lubricates more. Getting the glass ceramic surface after applying clear and streak-free, is almost impossible.
A pity, I find that cera-fix was often repressed at the grocery store shelf, although it is better by far (see reviews). I've recently discovered Budni in a quiet corner. But Still waters also run deep.
