### ⭐ YOU ARE NOt getting WHAT you think you are paying for, you have to buy an additional item
*by S***. on September 1, 2025*

I'm going to start out by saying when you see the worst smart you assume Dad it's all ready to go and ready to get it on the internet, you have to buy a separate item in order for you to get on the internet to control your fan speed when you're out of town or just not at home. This is very deceptive practices intern you're required to buy another item for $25 a piece in order to get on the internet, I don't think so I highly do not recommend this, I would say clear of this or you will get burnt you're not getting what you think you're paying for
