just wanted to chime in here and give some added input about this mic.
i would highly recommend this mic at the price i have it mounted on the wall about 13' away from my couch and it picks up everything i say with about 95% accuracy. The only problem i i have found is that sometime when i give an "on" command it will think im saying "off" and i have no idea how to fix this issue. but other then that great mic great price.
