Driver doesn't install on Windows 7 at all. On XP it installs, but not like the instructions say. The CD has multiple drivers on it, and you have to search through half a dozen other folders before guessing which is the right one. I bought because being more expensive than the five quid adaptors, I expected it perhaps just work with Sony cameras. But I don't get anything out of them with this connected, zilch. I can't rule out that it's me, but since it won't even install on Windows 7, I can't try my second PC, and it's academic since it has to be able to run on here. ### ⭐⭐⭐⭐⭐ Quality *by T***B on Reviewed in the United Kingdom πŸ‡¬πŸ‡§ on 10 April 2019* As with all Startech products, this unit is excellent quality.
