(update) CAREFUL IF ORDERING--- I THINK AMAZON SENT WRONG PRODUCT, WHICH SEEMS TO BE Portable 37 Keys Roll Up Piano Keyboard. AMAZON CUSTOMER SERVICE MADE GOOD ON MISTAKE.  Reveiew of that item also indicte the problem of the adapter. SO IF YOU GET THE CORRECT PRODUCT SHOWN, MAYBE IT WILL HAVE IT.

--- Haven't tried it yet, but no AC ADAPTER is included. Just the 'JACK' which indicates "DC6V". AC adapter needs to be purchased separately and adds to overall cost. Instructions state 4-AA batteries are reqd. Listed features on outside of box state 3-AAA are reqd. The winner? Curtain#1, which is 4-AA batteries.  I honestly don't imagine this is a `mobile' item for us, (wouldn't want to show up the pianist at our favorite restaurant), so a power cord for home use might serve best.
--- The packaging image of the "roll-a- piano" is not at all what was received, although actual item is indeed rubber and certainly rolls up to dimensions of approx  5"x5"x2".  (An idea for an ideal product would be keys that light up for teaching, along with simple lesson electronics)
--- Instruction booklet need major overhaul and is not written in well English very good. It also says the battery compartment has a screw, but it does not.  So if you're worried about small children, know that the compartment does NOT have hardware. (funny how it warns not to use sharp objects on the keys as it could cause `..fatal..' damage, but I'm quite sure it means permanent product failure and not risk to human life.)
--- Does using something with only 37 keys, ruin someone from ultimately learning properly on a standard piano, or is it a good start  ?.?.
