Long delivery time. Charging will heat up the connectors to a alarming temperature, so be watchful when charging this device.

There were a lot of twists and turns, but I received it well. The wind volume is strong and good for the size. I think it will be good for blowing dust.

You can press and hold to activate it, or you can press it twice briefly to use it in steps 1, 2, and 3. The wind is really strong!!!!!! Wow~~~ I will use it to blow away dust from my car and sometimes to dry my hair!!(^-^) ㅜ.ㅜ It seemed to work well... but it turns off after just going to step 3!!! !! ㅠ.ㅠ
