Pretty good! So Far......
I bought an external speaker off of e-bay, and it it pretty good. I cranked it up and put my first gen ipod touch right up to my ear, i could definitly hear something and it hurt a little. I have not tested it on bugs or mosquitos yet, i am looking for a mosquito or bug. Please fix clicking( it makes the high pitched sound then clicks to nothing then back then audible tones then back) so far so good!!!
