Fendi Spy Tricks to tell a fake?

What are the best tricks for identifying either, authentic or fake fendi spy bags?

I think that reading through the "authenticate this" thread and going to see a few in person are the best ways to get a feel for whether something is authentic. If you have a bag in particular you want opinions on, just post a link or pictures in the "authenticate this" thread.
