I've been looking at the unidaptor binocular adaptor, as well as the outdoorsmans binocular adaptor, and I have some questions.  The outdoorsmans adaptor looks pretty straight forward, but looking at the picture I really can't figure out the unidaptor version.  Does anyone have any experience with either of them on functionality or use?  They are about a 1/4 of what the outdoorsman adaptor cost, so they definitely have a leg up there. 
  
I will be using them on 10+15 Duovids.  Thanks, 
Jody
