I have one...don't remember if it came from WalMart or Academy or BPS, etc
It does what it is supposed to do...make jerky sticks about like slim jims and has 3 different tips for the flatter pieces of jerky.
Like JDR said, they are probably all made by the same bunch and just packaged differently. Mine came with the gun, the 4 tips, and a few packs of different seasoning mixes.
