It took me a while to get it myself. I thought SW111 was something else. I saw ///M5 symbol as soon as the page loaded but didn't notice that he made a mistake like that...
Yeah that took me a second the grasp the magniture of that dudes screwup. I thought he meant SW111 was the model of the keychain or the part number or something. WOW that was so stupid it actually boggled my mind.
I must admit... I first thought maybe it was an obscure model because NOBODY is that clueless, especially if they've got a key chain.... but then I lost all hope in humanity in general and realized that it's time to clean the gene pool...........
