Review: awesome value, has its tradeoffs - This thing is great FOR THE PRICE for the purposes of standalone noodling, travel, and at-desk MIDI/noodling. I have a real digital piano now, but I still have a lot of fun with this and noodle on it a little bit most days. I would definitely recommend it for learning or noodling if the tradeoffs that make this price+portability possible are acceptable to you! The voices are nothing to write home about, but they're definitely not toy keyboard sounds and are pleasant enough to enjoy playing for a while at a time. The mini keys are what they are. I wear a men's small glove; they're fine for me, but not as comfortable as full-size keys. Similarly, the three-octave range is just barely sufficient in combination with the octave switch. I don't think the instrument would be worthwhile in terms of portability without these tradeoffs, though. The touch response is functional; maybe a bit limited dynamic range and a bit quantized in terms of distinct volume levels, but it's fine for what it is. This thing uses remarkably little power. I keep a 1ft USB micro B to USB C cable attached at all times and just plug it into my phone, battery bank, laptop, or docking station. The main tradeoff for this low power consumption is a really sad little three-digit seven-segment display. The phrase recorder and arpeggiator are briefly neat to play with, but they're not really interesting to me personally. They're a bit frustrating due to the wildly different volumes between voices combined with the per-"channel" volume settings being limited and confusing. The speaker and headphone jack have a soft hiss to them. It's not very noticeable when playing, but you wouldn't want to record it. The speaker is mediocre at best in most aspects, but I'm happy it exists for lazy practice/noodling without having to grab headphones. MIDI works great with the same USB micro B to USB C cable connected to my phone or laptop. I only really use it for note + velocity input, but apparently a lot of the other functions like the phrase recorder, arpeggiator, and instrument selection buttons are exposed over MIDI as well. There's no memory for settings, but it's fairly quick to poke a few buttons on startup. For me, that's usually: power on, press PIANO to switch to the electric piano voice, turn volume up, turn octave down. If using for MIDI: shift+local control to off, shift+auto power off to disable.
Review: Best portable keyboard out there for its price! - Best portable keyboard out there! Excellent keybed! To me it felt exactly the same as the Yamaha Reface series's keybed. The sounds are really great, the pianos, the leads, strings - all of them. The recorder function is really handy! You can record 1 track + 1 arps track, so kind of works like more than 1 track. Can be powered by your iPhone (or iPad/laptop), and also with 4 x AA batteries. In terms of sound quality, keybed and portability, I would confidently say this keyboard is probably the best one out there!

## Questions & Answers

**Q: Does this keyboard have an auto-chord or one-finger-play chord function? (In other words it will play a C chord, just by pushing a C key.**
A: No.  It has an "arpeggiator" feature that created rhythms with whatever chord you play, but you have to know chords.  This is not a child's keyboard, this is a tool for musicians who are doing composition or arranging.  It does have very good sounds, plus it has a touch sensitive keyboard and MIDI connectivity.  It does exactly what I hoped it would do for me: it gives me quick, easy MIDI input into my computer; it gives me enough polyphony to input big, rich chord voicings; and takes up next to no space on my desk.

**Q: Is it polyphonic? In other words, can I play more than one note at a time?**
A: Yes it is 32 note polyphonic.

**Q: Is there a case made for this or a case/bag that would work?**
A: There is no dedicated case for this. If it helps, you might be able to find a small keyboard case, this product is about 20" x 2 1/8" x 8"

**Q: Can I use my cell phone charger to plug into wall?**
A: Yes

### ⭐⭐⭐⭐⭐ Better than I hoped for. What a great little keyboard.
*by D***N on May 20, 2026*

Wow! I bought this little keyboard to use at my desk with my laptop for composing and practicing. I have a Yamaha 67-key keyboard for performing. This little keyboard sounds a good as my big one. It works with my laptop and my amplifier so it will probably go with me to garage band practice. I can also use it as a midi. The piano and organ voices are excellent. Highly recommend!
