Funny funny order

My order came in,great. After opening the box and
pulling out the Sram Griphifters and 2 Sram front derailleurs,shinny
thing I didn't order at the bottom. Taking a closer look,its an anti
Chain Suck Device. Sticker says Free Gift. Okay I'll save it if I ever
get chain suck I'll try it. But the chance I ever get to use it in this
life time is a million to one. I very well know how to set up front
derailleurs. I keep my drivetrain clean and set up right. I use
the correct mm BB and I don't use Bontrager cranks. Shifters,front
& rear derailleurs on. So alls left is to order a 9 speed chain and
cassette to make it full Sram drivetrain but what should I do with that
chain suck device. Sell it or give it to some one that owns a Trek. Trek
was 2 bikes after the Huffy back in 96 - 98. 820 and 6500 and both chain
suck suck suck.
