I experimented with lures quite a bit in the last weeks and they work fine for me during feeding times of the animals. I tried them on Roe deer and was OK with the results.
Scents last longer than callers (20 ingame minutes, 10 real time minutes) and also have higher chances attracting animals in range (same range as the audible caller, IIRC. Also, after shooting a deer I also noticed the others were not running as far away as usual AND some of them returned to the spot as well.
So if you feel lazy and not like stalking around, that passive way of hunting can be a welcome change - and profitable...
