I don't personally have one, but I have a few friends that do.  IDChief was the most legit, very real looking, always scanned and blacklight or whatever.  If you get caught, it just means that you don't look old enough, at least with these.  reallygoodfakes made alright ones.  they took about 6 weeks to come, I think they were more expensive (do a group order if you can), and my friends got NY, so they were really flimsy.  They should be like this, but we all agreed they it was a little more than usual, but once they get a little dirty and used looking this is no longer an issue.  Varied reports of them scanning.  One person tested it buying a tin, and it didn't scan at their store, but they still let him buy it.  I think they work at most of the local scanners.  Also, you have to keep in mind that some bars do use fake tests just to see how you react, which is a large part of it. Some bars let you in with something so obviously fake its laughable.  It really depends on your location, where you're trying to go, and how old you look etc.  also you need to be able to back it up, aka have the info memorized and know the town/state you got it for.  /foreducationpurposes
