I bought my first recorder Zoom H2n in May 2014 with the aim of making choral concert recordings. Its relatively simple operation always satisfied me each time with a very good sound reproduction. Naturally listening must be on your computer to enjoy to the maximum the quality of the recording. Except ..... There are some weeks I noticed that the screen, starting dice became unreadable, transverse dark bars not allowed reading the menu in good conditions. I contacted Amazon to report my problem immediately agreed to share my recorder. I want to clarify that my camera was never shocked. In customer reviews, I read that a person had encountered a similar problem. So even if I recommend this recorder for sound quality, I put a damper on this technical defect which remains serious for proper use of the unit. Thank you Amazon
