This is a “tennis” racket that I bought at the Hypermart. You plug it in, charge it, unplug it, then push a couple of buttons and swing. Mosquitoes are really bad here right now. Yes I am keeping the windows and doors closed but they are so small they can squeeze thru the screens. I’m sure I look ridiculous swinging the racket around in the air but when it finally makes contact it makes a really nice satisfying crzzpp sound. Good exercise too! Notice I couldn’t resist the 1 yuan Panda Flyswatter either.
