I've been using Leatherique and my leather isn't "shiny" in appearance. It's still looks pretty OEM to me.
I don't know nearly as much about car detailing and care as you guys do, but based on Mutt's experience I'd have to side with him. I've seen him posting in here for a while and I think he really knows what he's talking about. I'm sure using the Magic Eraser ONCE or TWICE wouldn't really do much damage (at least noticeable damage), but consistent use will probably wreak havoc.
Overall, I don't understand why you are so persistent in your defense of the ME? Is it price? The results? I mean you could probably get similar results with a light cleaner and a microfiber towel. I've used a few products and have not seen this "shine" you're referring to, so I don't know how that is universal across the board...
I don't mean to get in the middle of your debate though
