This is a pretty decent little beginner piano for the money. Looks brand new (usually had a towel over the keys.) It is battery powered but you can buy an adapter for $10 on Amazon if you would like. I have changed batteries twice in the 18 mos since I purchased (new.) Maybe have 10 hours on it. Keys are touch sensitive (but not weighted) and do have some tension for building finger strength.
Selling b/c I'll be taking a class and want 88 keys. Has tons of features and pretty good sound bank, percussion, midi/headphones/sustain pedal inputs, etc. I never use any of that, bit it's there. Comes with the sheet music stand, the stand for the keyboard and the carry bag. I'm including the Panasonic Eneloop rechargeable AA's (3).
I'm not sure if it's Bluetooth capable - maybe? And, it only takes 3 batteries. Between the Amazon page and manual you'll get the info you need. Most other features (recorder, metronome, etc.) seem to be the same.
Was about $115 new, asking $50.
This is the TS-02 model.
