I got a small unit from Hobby Lobby and my problem is I try to look thru it like a riflescope with one eye closed then I have all sorts of issues getting my hands and eyes to communicate! I think if I could see more of the area as this unit has a small ( 3") magnifier I may have better luck but for $30 I thought it couldn't hurt. I need to play more with it and see if I can get it figured out as I'm starting to tie smaller flys now I just need to figure out how to get my fat fingers to hold the materials when working with the #20 hooks :-O Later,
