Super easy to install! I’ve been looking for a way to divert the air from a vent in my work space. Maintenance came and told me there was nothing they could do but turn off the air flow. I was then determined to look for something on my own! I found this product, and was able to attach it to the air vent with no tools! I have to say, the maintenance guy came by to take a look at the install and told me “no one in our school district has anything like it”. Now I’m special and my work space is more comfortable…. I’m not freezing from the direct cold air conditioner vent!
