Awesome adorable. I love it.
Color: White Size: 61 Keys
I love it so much and use it more than two other types of keyboards. I have awesome adorable.

Easy to use, and very robust! Definitely recommend!
Color: White Size: 61 Keys
My Take: A Beginner's Best Friend This piano is genuinely awesome. As someone who's just starting out, I was a little nervous, but this thing makes learning super simple. The LED lights and app are the main reason—the lights follow the rhythm, which makes it feel less like a lesson and more like a game. Plus, it just looks cool. What I love most is how convenient it is. You don’t have to mess with bulky songbooks or sheet music. The app has a massive library of songs that they keep updating with all the new hits. And because it’s so lightweight, I can grab it and play pretty much anywhere in my apartment. The sound is solid, and I can plug in my headphones for late-night practice, which my wife definitely appreciates. If you’re on the fence, I’d say go for it. It's totally worth the money and makes learning to play a lot more fun than I thought it would be. ... show more

Expensive Toy with Pros & Cons!
Color: Red Size: 61 Keys
Love this keyboard! My grandchildren & I can learn & follow along nicely! Only downside is the keys do not feel semi-weighted, at all! This makes it a bit cheap, while being very expensive! Also, you have to purchase the cord for your laptop, separately! Not cool, especially if you don’t have wireless WiFi options! I’m torn on the quality of the keyboard vs the price. Red color pops on the black stand I purchased separately! 2 things I do not like are the limited amount of songs & the sign in…it expires & all practice & accomplishments do not get saved! Bummer! ... show more

More and better than expected
Color: Red Size: 61 Keys
I purchased this thinking it was just the Smart Piano. When I got it as the "sing" version, I was surprised as I have zero talent for, or desire to sing. My son, who is accomplished stage performer, including Broadway shows, enjoyed it as he played and sang along. It's apparently great, but more than I need ... show more

Best Piano Ever!!

Best piano ever! Our family has the regular ONE piano and my daughter loved it so much that we decided to buy another and got the one with the SING option. Company has great customer service too! They have great color options.

It does exactly what I was expecting, great for learning notes and chords for beginners.

Mediocre at best, not worth the price tag.
Color: Red Size: 61 Keys
Honest review: It’s not everything it’s cracked up to be. And to be honest, aside from the build quality, there’s really not much functional difference between The ONE Sing and the cheaper standard The ONE. Same polyphony, same number of tones. One thing I expected on the Sing model was a mic jack — there isn’t one. All the functionality lives in the apps. Even the different tones are in the app. When the keyboard isn’t connected to anything, you just get a basic piano sound. Let’s put this simply: the price they’re asking is in the marketing, not the hardware. The ONE Sing is not a $340 keyboard. It’s very basic electronics for the sound engine, with MIDI added to play the sounds through the apps. There’s absolutely nothing special here. If you want a decent learning system with a keyboard that can actually grow with you, this isn’t it. Now, the apps. The piano learning app and the Sing app both require separate subscriptions. After a year, your total cost ends up around $550. And the Sing feature? Just a gimmick — essentially a karaoke function with chords. Look, if you’re getting something for a child to learn on, any cheap model with lighted keys will do. But these folks are trying to step into Roli Learn territory with a cheap keyboard. This pricing is targeted at people who don’t know keyboards. Don’t buy into it. For $40 more, you can get a Roland Go:Keys 3 with an app. If you want a keyboard with lighting to guide you, spend the extra $150 on the Roli 49-key piano with RGB lighting. I guarantee Roli’s learning app blows The ONE out of the water. ... show more
