Do no buy M2 Micro SD cards for this recorder- Unless things have changed.
6 February 2015
Summary: This is a good tape recorder. Just beware. When you want to buy an SD card to supplement the memory, just get a normal micro SD card - do not get an M2 micro SD - it won't work with this recorder. I know. Ridiculous, since the SD slot says M2 Micro SD.
Summary: This is a small compact device which seems to function fine. Recorded audio can be played back very clearly and I am very satisfied with it. Time will tell how reliable this device is, but so far so good. I had it for only about a month.
