...I purchased the minidisc recorder to listed to music while on long runs along the canal banks in the Phoenix area. The g-protection is worthless. It skips more than my [other]full size sony disc player. As for working out in the gym or traveling,  it's great. I don't recommend it for running. Because I bought this item for running, and its performance is poor for this activity, I am putting it up for sale.
