  1. 5 Star Review

    recording my boss

    This is a great item to have in terms of documenting conversations and then writing out specifics. I work in a place were new boss's have come in and they are trying to fired all of us. They promise things but do not deliver. Now I do not have to immediately write out the notes or our meetings. I can record them and then pull out the more pertinent bits that will keep my boss's attention

  2. 4 Star Review

    Records very well

    I am using this device while on (police)patrol. So far, not disappointed. Audio is very clear and it even picks up wind noise from passing cars and mother nature. Only two things I am concerned about:
    1. I off-load audio files to computer after each use. When plugged into USB, it charges for the few minutes while off-loading; will it cause the battery to develop a memory and not fully charge? Should I totally discharge battery and start fresh each time???
    2. I wish the audio files had a date and time stamp embedded so I do not have to listen to each file locating the one I need. From now on, upon activating, I will 'voice' a date and time into my recording.

    I cannot give it 5 stars because of the battery charging issue. So far, a good product though a wee-bit pricey.

    Works very well. For how long?

    Upon reception I was pleased to find out that the product worked as well as advertised with a clear sound, even from a distance. I cannot give it a higher rating though, as I do not yet know how long it will last without failure, and how long the battery lasts when recording. Overall, even if the price is very steep, it serves its purpose.

  4. 5 Star Review

    We found out what was really going on

    This product exceeded expectations. We didn't know why my grand daughter was so anxious about spending time at her other grandmother's house. This has been the subject of a lengthy court case. Now we know.

    Sound quality is excellent, even stuffed inside of a coinpurse. The files were easy to access, and the battery life is as advertised. No disappointment here!
