1. Working Theory: only female mosquitoes bite human or animal especially during their breeding and spawning season,they are annoying of male mosquitoes' or dragonfly's sound,so they try to stay far away from male to avoid 2nd time pregnancy. This smart Ultrasonic Mosquito Repellent simulates oscillating waves(ultrasonic) frequency emitted by male mosquitoes to drive female mosquitoes to protect human.
2. Physical Drive: this product's intelligent chipset makes safe microcomputer ultrasonic frequency to emit 360° ultrasonic wave,electromagnetic wave and bionic wave. Those waves interferes with female mosquitoes' auditory and nervous system so as to drive them away(not kill). The effective space cover range is 3- 10 ?.
3. Chemicals/radiation-free: this smart Ultrasonic Mosquito Repellent doesn't emit any chemicals and few radiation, it is safe, environment-friendly and healthy enough for human especially baby,pregnant woman,old people etc..
4. Portability & Convenience: equipped in the soft silicone wristband,it is movable and portable with human body, we can wear it on hand wrist or leg ankle for home and outdoor camping,fishing,walking,riding and climbing etc. It's free from mosquito harassment,we can enjoy happy parent-offspring times with our kids. It's built-in 5V DC power Lithium battery can be used continuously for 5 days after fully charged and 1 month stand-by,one 30-munite charge can be continuously used for 30 hours.
5. Efficiency: If used in the same quarantined environment for a long time, mosquitoes may have certain immunity. Test results show that this product can not gurantee to 100% efficiently drive all mosquitoes,but it can significantly reduces 80-90% mosquitoes bitting activity, and its effective rate is possibly different according to different environments.
