Q: what is the closest distance you can use this lens for?

BG411553924 Up to 30-40 Ft is OK, but why would you buy for close distance when you can see without any device?

BG411553924 Of course! it should suppose to turn off the Wi-Fi power source as it is directly connected to USB audio output through cable.

BG411553924 Dear friend, I don't think they will ever redesign it with the EU plug. But it is a simple fix by buying an adapter. Anyways I will not recommend this unit as it has a design flaw. The problem is that transducer used in it for the high frequency sound is not compatible with the audio output chip. Therefore the sound dB is very low and does not work properly on a higher pitch (above 40kHz). as you know the effective sound waves are proportional to the size of the subject so the mosquitos are not repelled.

Q: Do you have the spectrum analysis available for review?

BG411553924 There is no requirement for the spectrum analysis as it has been performed by several peoples in the lab. The resonance frequency should be proportional to the size of the object such as bacteria etc. The best result was found was 254.4 nm wavelength of the light which falls under UV of the light spectrum. I hope their bulb emits close to that range. I just bought one and let you the results.

BG411553924 Yesit is OK to do that, as it varies from 40K to 62K and green LED flickers accordingly indicating the system is functional. The reason behind is the resonance of the size of the creatures with respect to the sound frequency. It covers the full spectrum.

BG411553924 It is a single unit, but can be used in left or right ear by rotating the head by 180 degrees.
