After I've had good experiences with adapters (Mono and Baby) by another manufacturer here has convinced me of the price. Unfortunately I took the negative reviews seriously and thought to myself "For me to be working already." Well. So far, three devices tested and when the adapter could be actually used. A very strange design was chosen for the adapter, so that in most cases, no contact can be made. Well. As long as I still have my good adapter I can use the cheap parts at least in selected devices.
