This is a great digital note taker at the price. And it is reliable Sony. It is very intuitive to use, with easy set up from the menu. It has got a large memory, so you will be able to record for hours on this. But I found it limiting. what is doesn't have is any ability to link this up to a pc and download your sound files to the pc for storage or for editing. It comes without microphone though it does have built in one so you can use straight out of the box and it doesn't have an earphone, so if you want to listen to your notes without disturbing others you need to get one.
If you cannot dump the files onto the pc, then there will come a time when you run out of space. Admittedly, that's a long time away, given its capacity, and you will probably be quite willing to erase files before that ever occurs. But I think the ability to link to a pc and transfer files is pretty essential unless you use this for just keeping a certain volume of notes. There are three folders on the recorder, A, B and C. so there is some minimal ability to keep things sorted.
Great value for the money, and very light in the pocket as well as on the pocket. Its hardly any weight at all.
Just be careful that you want this pretty basic model before you buy. Its good value, I gave it a four star rating but be sure you want something this basic before going for it. Battery powered, so cannot be charged via usb port- another drawback- or is it- depends on your point of view again, I suppose
