Personal experience of the author:
Overall, the RS-M253X is a pretty solid, neat sounding recorder. Weaknesses are most likely to be found in the drive, which, due to the simple design, is clearly inferior to recorders with a double capstan drive. An eye-catcher is undoubtedly the level indicator, which is not only visually well done, but also resolves quite finely.
A nuisance, on the other hand, is undoubtedly the digital counter, which can be set to real-time display during playback, but then immediately jumps into the three-digit counter mode during rewinding and rewinding - and stays in this mode as long as you don't dial real-time again at the touch of a button. Very annoying, especially when searching for titles!
There are separate microphone inputs (mono jack) for the right and left channels on the back of the device.
Headphone output unregulated on the front
Only RCA connectors, no DIN
