By means of an electric vernier caliper I have measured it several sheets and the deviation was in the range of the measuring tolerance of the vernier caliper. From this I therefore deduce that the leaves have been working very closely and you can rely on the strength eingebrägten indication.
The leaves, however, are relatively narrow, what you want to set the entire bit more difficult when it depends. For my purposes it is sufficient, however, very good
Supplied she came heavily oiled, but this is normal with feeler gauges due to the corrosion protection and just as it should be kept really well. However, since it does not arrive with me at 0.05mm I refrain.
Conclusion: All in all, a very good product at a reasonable price. Works just like you'd expect it and was made very precisely. Therefore, there is of me 5 of 5 stars
