Quality is good for a 4 yr old to be introduced. For the people saying the sound is off… look at the price? What do you expect? Comes w a usb c connector but no block. Takes 3 AA batteries. Color is black and white. Volume is ridiculously loud. Put take over the speakers. Every time you turn it on it goes back to default loud AF

Multi-featured product at a bargain price.

My grandson appreciation was priceless .Size was perfect for him.

Okay, for the price, this has so much. I got it for my three year old at the time. He doesn't quite understand exactly how it works, but push button/make noise. The only problem is it's max volume is pretty loud and it turns on at max volume. Its also a pretty big button and one of his favorites for my son to push. So every time I turn it down, he accidentally resets it. From the basement, you can hear it from anywhere in the house. I gave it to my sister's kid within a few days. Recommended for children brighter than mine.

It was much smaller than I expected, so please look at the sizing. And the quality could have been better. The kids used it for a bit then the back part where the batteries are broke.

She's too young to play, but she loves to "play" my piano, so this is a starter. My daughter keeps it put up until she's ready to supervise play, and the baby loves it, including dancing to the prerecorded beats. It'll be ready for her to take lessons when she's a little older, and is durable enough that I'm sure it will still be working.

Using for daughter who is just starting to play piano

Just got it today. It's cute and kind of charming, but it plays many chords incorrectly. This explanation may require a bit of musical theory knowledge of chords, but I'll summarize it here and give a fuller explanation in later paragraphs.Here's the problem - play a major chord in the root position (1-3-5) - it plays correctly. Play a major chord in the first inversion (3-5-1) - it adds a minor 10th (3-5-1-b10). Play a major chord in the second inversion (5-1-3) - it plays correctly.For the minor chords, it does something similar, but messes up the second inversion instead of the first inversion.Will a three-year-old who's not a Mozart prodigy care? Probably not. The harmony issues are a little advanced for someone more likely to be drawn to the frog, bird, duck, and dog sounds.But, here's why it matters to a musician or someone wanting to use this as a convenient study tool:We have a full-size acoustic upright piano. My wife plays well, but only by reading notation on the staff. She does not yet improvise and is beginning to learn more about music theory - particularly chords and inversions. She wanted a small keyboard she could play at the kitchen counter with the idea of using it to learn and practice chord inversions without sitting at the full-size piano. Once she had that knowledge, she planned to save the keyboard and give it to our young grandson when he's a little older.But when I started testing the keyboard, I ran through the inversions and realized that something was seriously wrong with the sounds. If you are familiar with the notes of a piano keyboard but not so familiar with the numeric notation above, here's how it works on this keyboard:The C major chord has the notes C, E, and G. If you play those notes in order from left-to-right on the keyboard, and hold them down together, you are playing the C major chord in root position. If you then hold down E, G, and C from left-to-right, you are playing the C major chord in the first inversion. In this inversion the E and G are in the same place as when you played in root position, but in the first inversion the C note is played an octave above the C in root position. BUT - if you do this on this keyboard, it adds an additional note to the three you are holding down. In this case, it adds the Eb above the C you are playing. So you are hearing E, G, C, Eb. It's no longer a C major chord. Like I said above, it mangles the second inversion of a minor chord, too.Since hearing what you are playing is part of learning about the keys you are playing, this is not a practical way to use this device. On another note (heh-heh), at first I though it might be fun to bring it along to a campfire jam and play a few chords along with the guitars and mandolins and so forth. Not now. (Unless I want to use if for well-timed duck quacks and such!)Too bad, since so many other aspects are pretty decent. It has 8 rhythm patterns with a tempo control. It would be neat to be able to practice chord progressions along with the beats, but you'd have to give up a third of your three-note chord options.Anyway, our grandson is still too young for this, so this one will be returned.
