Conclusion: good, cheap, accurate The product corresponded to the figure. I needed 4 pieces (for each car in the family one and 1 Erstatz) and bought due to possible fluctuations in production for safety's sake 6. To prevent damage due to incorrect Polungslötung I have all through previously measured and could happily find no errors. Although the adapter is not perfect but good enough on the can. Measured by the use of materials, there is no reason why such an adapter should cost more. So I would not call it cheap. However, I expect no quality materials. The long-term test remains to be seen.
