This fan is the best of the best. It’s super easy to install and you only need one tool and it’s included! Before you use it you do have to charge it for about 5hours but you can use it while it charges! Once it’s fully charge the life time of the battery is up to 20hrs! I honestly love it because it’s super quite even at its full spreed and it converts into a countertop fan! I’m excited for the summer to try the attachable mist cool!  Overall the performance and quality of this fan is amazing.
