I wouldn't worry if something seems outdated. If it's performed nicely then it's performed nicely and that's really what matters. Personally, I never got the coin bite. I don't like to put money in my mouth and I don't think it makes sense to bite a coin. It seems the effect is in the restoration and not the bite. I prefer those oreo cookies that you can bite and restore. Same concept same method, but it seems more realistic and you have an excuse to bite the cookie (It's a cookie) and restoring it is nice because now you got a full cookie again.
Just me.
