Summary: Sound quality is good, but on/off switch is difficult to use. Battery life diminishes rapidly if "on" is left active for even a short period of time, resulting in numerous battery replacements (batteries ordered from B&H, too). Clip has no spring action. I've purchased a Sony microphone that has none of these problems.
Summary: I am a musician, I bought one, I cannot use it, the sound is smaller than the noise even I turn up to the full/ max volume. It is likely the kid toy. If you need it I will send you as a friendly gift.
Summary: This is a horrible item. It doesn't work at all. I bought it brand new and it looks like it should work fine. When it's plugged in and recording, it makes random loud clicks that send the audio meters to red. If that wasn't bad enough, in order to get it to pick up any audio, the gain (on my computer) has to be up as far as it can go and I have to hold the microphone within two inches of my mouth. Maybe I got a defective product.
Summary: Other than the power switch is not easy to see, the most issue with this microphone is the sound quality not that good. Use this microphone to record music for sure will disappoint you. Even using it for church meeting recording, you would not get excited for its sound quality. If you can tolerate the size of Sony ECM-MS907, you may like the sound quality of that microphone. If you like a small lapel microphone with true voice, try the AKG WMS-40 wireless system.
Summary: I bought this as a preacher and a speaker to digitally record my messages. It has a niche in the back that you turn with a coin to turn it "off" and "on" but you never know it's on until it is to late. Save yourself the trouble, buy another one besides this one.
Summary: Unfortunately, at least for me, this mic performed poorly - had to return it. The only way to get a clear recording is to have it sit PERFECTLY STILL. If you so much as touch it or move it, you get massive interference that drowns out (in my case) the voices you're trying to record. Tried it in several orientations - clipped to my shirt, clipped in a pocket, etc. None worked. To be avoided.
Summary: Understandably, the other reviews express their disappointment in the fact that the mic does not come with a battery - so you'll be needing a CR-2032 battery along with purchasing this... NONETHELESS: The value is unbeatable. I used the mic extensively with Griffin's iTalk & my iPod to record motivational lectures, and the sound quality was significantly improved vs. not having used a mic with the iTalk.
