I use them. They are awesome. They are fairly simple to put together so I just put the blades on when I get into my blind. that way I can put the arrows in the quiver like normal, then I set the ready arrows off to the side until I see a bird coming. They fly great if put together properly. I put the blades in the orginal case and put a towel in with them so they dont make noise or get dull. Hope this helps and please ask any other questions you might have.
