I didn't use one until AZ made night hunting legal. I got my first one to try and keep disturbances to a minimum, including law enforcement contacts at night. Now I have 3 of them and when I hunt states where they are not legal it feels odd.
The biggesr benefits are being able to hear my stands clearly and quick follow up shots. Length and weight are the only serious drawbacks I see.
Good luck and good hunting...
