As soon as it came out of the box i was dissapointed. Have had a lot of experience with TASCAM, reel to reel and digital field units but what I was holding is a cheapo Chinese plastic recorder. Having said that, the sound ability is a different story. Some amp noise on record but anything above the background noise floor comes out true to life so proximity effect in normal record is OK with the built in mics. The plastic cover over the MICROSD card slot might not last long with lots of opening and closing so transfer files using the micro B USB port. All in all, a basic atmos recorder
