I really meant to make a better review than this but I just don't have the time to do a better review and they are releasing there second batch of cables today. So for anyone who cares here is my 2 cents.
First off the build quality is top notch. The cables are very thick and properly shielded. This does make them a little harder to bend around corners but unless you are real tight on space this should not be a problem.
As for video quality it is what you expect for a good RGB to Component conversation. Also the brightness switch is nice if your system's video is a little dark.
The cables plug in nice and snug not too tight and not too loose, baby bear would be proud.
The SNES cable also works well with an N64 with the RetroFixes RGB amp mod. With the N64 I noticed an improvement over S-video. It was most noticeable in Dr. Mario 64. While playing on S-video my eyes would get fatigued really quickly on component this was not an issue at all. I'm not sure how to describe it better than that. Looking closely at the screen I didn't really see anything like dot crawl that I could easily describe as the problem. But my eyes reacted drastically differently to each cable.
So in summary it you have a TV with component inputs and don't already have a big investment in RGB cables and hardware, then these cables might be for you.
I will gladly answer questions but probably not today. I'm on my way to one of the best beer tasting events in Pittsburgh, the Big Pour, for 3 hours of unlimited craft beer goodness. So just imagine my responses as "That's what she said!", Just spelled much more poorly.
