I use it in my 2003/2004 Bosch, otherwise glassware ends up with spots and streaks. The 'Extra Drying' option is activated too, where the final rinse gets a slight boost during heating. Stainless steel tank throughout. This machine seems to require handling with kid gloves; it is very sensitive to conditions being 'not quite right'.
In my parents' 2013 Bosch, same as above, but we noticed that when we tried to reduce 'Extra Drying' to 'Normal' and/or reduce rinse aid to a lower setting, the crockery was still very wet the next morning. I put this down to the use of a polypropylene 'Polinox' wash-tub base, attached to the stainless steel walls. This machine dries very well with 'Extra Drying' switched on, and the rinse aid set to the factory default setting. Wash results are very, very good in this bottom-of-line machine.
Regarding rinse-aid testing, the German consumer group, Stiftung Warentest (test.de) tested rinse-aids last October (see link). Google can translate.
The article is partially subscription-locked, but the main information is on the first page. Results are not available, but Lidl.de
https://www.lidl.de/de/w5-klarspueler/p262274
reveals their rinse-aid to be a good performer.
The general info, is that the surfactant level needs to be 5-15% in order to be effective. Less than 5% is no good, apparently.
Courtesy of test.de:
"Tip. Look for the list of ingredients on the bottle label. The tested rinse aid with less than 5 percent surfactant content is not recommended. The good ones in the test declare 5 to 15 percent."
