I thought I would buy this product as the price was so good, what did I have to lose. Arrived rapidly which was excellent, packaged well. Easy to use just charge up in usb port, and go! Initially worried about how much recording time I would get, no problems at all have received so far 10 hours at a time recording after afull charge. Just be sure to transfer any recordings you want to keep, so as to keep the usb stick empty to achieve full recording limits. All in all a brilliant bit of kit, clarity of recordings, could even hear people breathing, and ease of use 1st class item!
