Refurbished SONY Microcassette Tape Recorder - Working / Used Unit M-100

SONY Ultra-thin Microcassette Tape Recorder, Serviced, Working, Used Unit.
Model: M-100, Made in Japan.
This unit was among the world's smallest tape recorders when released, competing with other manufacturers. Excluding the battery compartment, it's almost the size of a credit card (see photo 9). How about it as a working collectible?
Dimensions are approximately: Width 60 x Depth 117 x Thickness 13 mm.
Features a sleek, all-aluminum exterior.
Selectable tape speeds: 2.4 cm/sec and 1.2 cm/sec.
The rubber belt, crucial for tape transport, has been replaced. The internal mechanism is mostly metal and precisely engineered like a watch.
Recording, playback, fast forward, rewind, AUTO STOP (powers off when tape runs out at either end), and pause functions are all working correctly. It has a built-in speaker. It does not have a tape counter.
Both MIC and earphone jacks are 3.5mm. The MIC is also built into the unit and has been tested.
Comes with the original soft case.
Uses 2 AAA batteries. The battery compartment is clean with no rust or dirt. The exterior shows signs of age, minor scratches, and dirt from use.
Microcassette tapes are still sold at electronics stores for answering machine use.
Although it's an old item, it works properly. Thank you for considering it.
