I agree w/ Milo. It looks like the old Wasp's I use to use.
They came with the Xbow I got for the girls.If it's good it's good. The price isn't what kills the deer. I think they look pretty good.
Come to think of it, there was a head sold under the name of game tracker that also used those collars. Like Koplin and Allen, they were sold in Walmart type stores too. Probably all the same manufacture.
