Fake application. Please don't download this app. A pioneering study testing five different ultrasonic devices against four mosquito species convincingly demonstrated that ultrasound in the 20-70 kHz range used by these devices had no effect on reorienting flight by female mosquitoes either toward or away from human subjects. Additional tests have shown that sound generators capable of a wide range of frequencies were also ineffective in repelling mosquitoes. The fact is that these devices just do not work
Don't bother with it, turned it on and mosquitoes were still flying around me. Pretty much useless
Berguna banget. Boleh-lah!
