Some time ago, it was still in midsummer. It was very hot and there were many mosquitoes. Suddenly, I found a product called mosquito killer that was very hot. So I did a hand training during the National Day. The whole is very mini and can be easily taken out of the door. When using it, pressing the switch will bounce up. After using it, just press it down. The upper part is equipped with a pull ring, which can be easily carried or hung on something for use, using a type-C power supply interface.
