This rinse aid does its job in the interaction between tabs and salt of the same brand but also other brands very well and there are no complaints.
However, this rinse aid is very high-priced and not necessarily better than Discounterklarspüler.
Positive is the stability of the bottle, this is at 750ml content quite large and the dispenser lid.
In Internet makes Amazon, in free delivery understood the best price of just three euros for 750 ml bottle.
For product I give 5 stars for the price 3 star overall so 4 stars
