This is a pre-owned item. Please see photos for details, condition and measurements. Measurements are approximate. I have put a brand new battery in to the keyboard to test. It played very well. There was static on volume level 2 I believe. But all other levels of volume, including the loudest played level, were very good. Also, i do not know how to test all options on this keyboard to guarantee working condition. For that reason I am selling as is / for parts or repair only! One more thing, the fuzz on the back of the battery close piece deteriorates when touched. Any questions please feel free to ask at any time. Thank you kindly for your interest in this item and have a great day!!
