Handle: This is usually between 7 and 12 inches long. Some handles have an ergonomic design or nonslip grip for easy use.
Head: The head size depends on the racket, with some models being larger than others. A larger head means more surface area for killing pests without needing to be precise. A smaller head requires more accuracy when using the racket.
Electric grid: This is often made of wires, while the head and handle consist of hard plastic. On its own, the grid is somewhat durable, but it can get damaged if you use the racket like a traditional flyswatter.
