It does what it's supposed to do - convert the SCART output of, say a DVD player, to HDMI format. It allows us to use an old DVD player (or even a VCR) with a new TV which doesn't speak SCART & needs an HDMI input.
We bought this to connect our really old (but perfectly OK) DVD to our new TV that didn’t have a SCART socket. Despite many hours of trying, unfortunately it didn’t work and we had to buy a new DVD instead. Don’t waste your money!!
I needed this for my DVD and I thought I would get a better picture quality than I have, even tried it on a different television. The picture quality is not as good as a straight scart from my sky box to the scart on my TV. It does the job and not drastic, just okay, plug in and go
