This easy to use device is of unquestionable efficiency; as soon as the insect is affected it is struck. The build quality seems very good and justify the price difference with other cheaper offers. The only difficulty in the use and quick due to the erratic nature of flying insects such as flies or mosquitoes, which greatly reduces the chances of hitting them in flight; it is best to try to touch on takeoff. This is however not a fault of the camera, because the use of its competitors or a simple fly swatter faces the same difficulty. In conclusion: very recommendable purchase.
