Review on Lightahead Portable 61 Keys Roll-Up Flexible Electronic Piano Keyboard: Full Soft Responsive Keys Synthesizer with Built-in Speaker – Ultimate Portability & Versatile Performance by Mike Messerly

It only got four stars because my expectations were clear and it is inexpensive (i.e. you get what you pay for). If you play one note at a time and can hit the sweet spot each time, it can play a lovely tune. It can not play cords. When you try to play a cord it very quickly plays each note separately so you hear separate individual notes, not a cord. It does not hold a note, If you keep your finger on the key with the intent to hold a note the note will play several time. This can get annoying.It is light, it will pack well. I purchased it because I will be traveling for a month and don't want to forget everything. It will probably help with that although I may turn it off and pretend to hear it. It should make a fun toy for a kid.
