the hands free model you can leave on the heating element in between tokes if you want, making it hands free, but you can still take it off and use it like a regular whip. you probably dont need the hands free model but its just nice to have the option, it makes it easier for people who havent used a vape before.

PS. if you havent already ordered it i would consider liking into a vapor warez. they have a much better warranty.
