Summary: This is very handy and priced right. I purchased as a gift for a friend's 11 year-old son. He has no problem operating it, so any adult should find it intuitive and helpful. Has three easy to use "folders" and will store more than 500 hours of voice. Compared to higher priced models from competitors - if all you need is a record and play-back device - look no further.
Summary: I figured Hammacher Schlemmer did the studies, and thus this was a good buy. Well, it is capable, but nothing to rave about. The volume is limited, so that you have to hold it next to your ear to fully hear it well. Also, they call each entry entered separately, a "file" - well, perhaps, I would call it just an entry. A bit complicated finding the right entry "file", but then, perhaps I am just too old for all the digital ins and outs of these kinds of things.
Summary: I am a computer literate person. Was able to install date & time. But that is all. After an hour, I gave up. Each button has several functions, and it is unclear from the instructions what and which! Got one recording to work, but the quality was atrocious. But could not repeat it. It needs more buttons, and much better instructions. I finally returned it. DONT BUY THIS!
