Apparently but no mon product ...

I opted for the Oehlbach Adapters because products of this brand are very high under normal circumstances, but this is exactly the opposite is true. (When I had ordered, there was no book reviews)
When the adapter to 5 different 3.5mm plugs was too tight, I thought that this is a Monday product. The adapter I returned and was about to order a new and have realized that it is apparently not an isolated case.

It is a joke, as the adapter may come at the price of quality control.
