That was my understanding. You could leave a deposit and take one for testing. If it worked, you had to order a normal prop in that same family / pitch, and bring the blue one back. I have not seen one in quite a while, but then again, I havent looked either. Seemed like a good idea when I saw it… BTW, for the link given, that might not be a bad deal. Any good prop shop (or yourself if you want) can polish that thing up, or sandblast it for a satin finish, and get rid of the ugly blue coloring. 125 bucks for a 26p spare prop is not half bad.2008 Pantera Classic2014 Mercury Pro XS 200
