I tried it last fall, and probably won't this year because:
1) Depending on eye dominance and how your particular optical hardware is wired, you may find that your eyes don't quite track together. Put a dot-sticker on the wall 20' away. Both eyes open, red dot on the sticker. Now alternately close each eye, and see how much your brain "corrects" the position of the dot between them when synthesizing the image. You may be lucky, or you may not. In my case, the difference between the synthesized compound image and the individual ones is too big.
2) My tag was for antlerless, and my distant focus isn't the greatest, so the lack of magnification cost me time spent watching to make sure there were no little 4.1" antlers on my intended victim. A 4x magnification would have let me make that call more quickly and surely.
And more practice, better technique, and a properly bedded rifle would have let me hit her, but that's a different problem.
