I'm a bit confused about what you're actually confused about. I believe the listing is quite clear (not to mention "Replica" is a synonym for "fake"). Even listed the website they were purchased from and my personal experiences using them. Oh, maybe you thought someone was giving a deal of the century and selling an Elcan for $100? Or were you just wanting to clarify?
If there wasn't a market for them, the number of videos and reviews out there showing them used on actual weapons wouldn't exist. If you're not interested, I don't even see the need to comment... but to each his/her own. I wouldn't recommend them for your trip to Afghanistan... but they function well.
Thanks for the input! I hope this assisted in clearing up you confusion!
