I know what you mean about the looks as I agree totally. I will say after giving them a try, I have been using them for three years and really like them for predator calling. Much easier to use and versatile than regular bipods. I have them on all my predator rifles.
I can see the functionality, for sure. It certainly beats having to carry a tripod or other separate support. One of those 'ugly but effective' type tools, I imagine, but I have not personally used one.
