The large number of positive reviews and the reasonable price (a brand device costs like 40 times) have then convinced me from buying.
The shipment went Amazon typically fast and I could not wait to try the device. The first test I've done at home on a TV with VGA input:
Cable in the Tab -> the Tab provides instantly and automatically to the image output -> connect to the TV via VGA cables -> image is transferred clean and flawlessly
For use with a projector, I can confirm that as well.
Of course, the resolution by the VGA standard is limited, but that should be clear to anyone who buys VGA. It's an old standard equipment.
Conclusion:
The adapter does exactly what it should. He is neatly processed, small and light. For the use of tablets with MicroHDMI outputs at various VGA devices it is an inexpensive and functional solution.
