I have one but dont use it anymore.
I agree they can be benificial, but I hate dragging it in the woods.
Funny story though.
9 years ago I was using it on public ground.
An older man with a crossbow stalked withing 40 yds of it (often raising his xbow)
I was gonna let him shoot it ,as I wanted to see the reaction.
He finally realized it was plastic... then he started looking around.
Once he spotted me in the tree he walked away without waving or nodding his head.
I could hardly keep it together in the stand
