i use it and think it helps to a degree. showering in anti scent body shampoo and using scent blocker deoderant is a big plus i feel. using cover scents like drags to your stand soaked in doe pee and scent wick(s) set up around your stand aslo can help mask your scent. playing the wind is probably the most important. i also carry a spray bottle with me with cover scent. this is usually made of pee cut with my pee. works great on scrapes and other veg around my stand.
