Good..^^
It has five speed levels and although the blowing power is not impressive, it will definitely bring relief on a hot day. The set includes a short charging cable and a lanyard with two strings for attachment, so you can wear it around your neck, for example. I can't comment on the battery capacity or operating time because I've only had it for one day, but the most important thing is that the sound of the motor is tolerable.
It has good power, this is the second one I've bought to have in the office.
It's been a long time since I've come across something truly good. It's lightweight and the air comes out cool.
There is also a strap that can be used to hang it around the neck, allowing it to be attached to both sides of the device and worn around the neck. It's lightweight, so it doesn't seem like it will put any strain on the neck at all.
