FullSet publishes market-by-market guides to OBD2 adapters, diagnostic scanners and battery testers. Each site is written in its own language for one market, because which device fits depends on the cars, the apps and the merchants of that country.

Tests, comparisons, vehicle compatibility and problem guides for the German market.

In preparation. The Polish edition opens once its catalogue and sources have been verified.
We classify devices from manufacturer documentation. We run no laboratory, so we publish no ratings and no measurements we did not take.
Compatibility changes with app and firmware updates. Each classification carries the date it was last checked against its sources.
When we hold no verified merchant offer for a device, the page says so instead of linking anywhere.
The details are in our Review Methodology, Editorial Policy and Affiliate Disclosure.
