Great buy! (A few setbacks)
Honestly one of my favorite purchases. HOWEVER, I’d like to get the one negative out of the way. I was planning on using this as a midi controller along with it being a fun portable option. There’s no midi port!!! Listen Casio, I get it we’re trying to further things technologically but if I don’t want to buy a $60 Bluetooth midi adapter, I shouldn’t have to. ADD A MIDI PORT!!! That being the only negative, I’ll start with the sound quality. Right out of the box it sounds great! Such nice tone. The keys are sensitive enough to where you can tell there is quality. I would have loved it to had come with a sustain pedal (even a cheap one would have been fine...) but I went ahead and ordered one today. Sound quality is beyond what you could expect of a portable and very affordable keyboard like this. The sounds it comes with are strong to quite strong. The only section I would say it could use a little more variety on is the actual piano sounds. Maybe instead of having 8 piano sounds and 16 electric piano sounds, they should have gone 8 electric piano and 16 piano. Other than that very happy with the preset sounds. Portability is great, super light, and I love the fact you can put on straps and hold it like that. The usage of the piano and figuring out how to get it to work is very easy, anyone could figure it out even without the instructions. Lastly, my favorite part about this product is IT’S BEAUTY. But really, this is a great looking keyboard. Personally I went with the red option and it is so slick, the red(which I do recommend) gives a great mix off a retro and slick conciseness feel to it. Over all I’d give it a 4.5/5 and would recommend. Thanks for the great product Casio!

Simple, Good-Sounding, Best Deal!
I've had this Casio for 6 months now, and have learned how to play piano/keyboards on it....and have no intention of upgrading anytime soon, because this thing is great! It's just what I had been looking for- just a simple basic electric piano/organ, without all of the endless nonsense that all the other ones seem to have...and most important of all, the piano and organ voices sound GREAT! I don't need accompaniment, and rhythms, and 600 voices, and all of that crap. With this, there's not too much to distract you or get in the way- yet it odes have a ton of useful features, such as octave shift. I love that it is not festooned with dozens of buttons and displays. You access the additional features by pressing a program button and then hitting one of the 61 piano keys. Every key does something different; and every key also turns on another voice (in conjunction with a different button)- but the beauty is, to look at it, it's just a simple, clean keyboard with only a few buttons. Playing this thing is addictive! The one thing I dislike, isn't the product itself, but the manual- or rather, lack thereof. It comes with only a cheesy fold-out, small-print basic starters guide, and you have to access the actual manual online-which wouldn't be a big deal, as really, you can just turn it on and play...easy-peasy...but the thing is, to access the features which are controlled by the piano keys, you have to refernce a chart, so that you know which key does what; and also which key implements which voice, as there are no markings on the unit or the keys. Don't let that dissuade you from buying, as this is the best keyboard you find for anywhere near this price...but it would be nice if it had come with a proper booklet style manual- or at least a decent quality chart showing which key controls what.

Great sounding keyboard, great value!
For the price, a great at-home practice piano for my teenaged daughter. The sounds are very good, it's easy to use, lightweight and compact. She hasn't tried performing with it outside or using advanced features such as midi but leaves it set up in her room and plays it regularly. Very happy with it.

Holy Moly! Don't let the price deceive you.
Love tbe portability and unique design of this instrument. Has an expensive look to it. The sounds are amazing for this price range. I don’t miss weighted keys at all with this. The keys have a matte textured feel and they are touch sensitive. Lots of great hidden features on this keyboard. Tone layering, octave shifts, etc. If you want great sounds and aren’t wanting drum beats and accompaniment then this is a great instrument. I love that you can use batteries and take it anywhere. Played it in my backyard and my neighbors were coming out to listen! Update: Loving this keyboard more and more as I delve into the full instruction manual (available on the casio website). I recommend printing for easy reference, as there are a lot of hidden features. I just discovered the hidden piano and organ tones, along with a piano/bass split. The organ tones are KILLER> if you love vintage sounding keys (wurly, rhodes, pipe, and gospel organs...even has a nod to vintage video game organ tones). My new favorite features are the simple record/loop feature where I can record one hand playing and then play the other hand over it. Super helpful for learning Bach pieces especially. This keyboard is exactly what I was looking for in that it has super impressive, high quality sounds/tones in an inexpensive keyboard. I love the styling on this. It is quite unique and premium looking with its fabric covered speakers. I think its great that it comes in 3 colors. I often find arranger keyboards a little cheezy and I really just want to play sheet music where I play my own accompaniament. The recorder feature allows me enough layering capability for my tastes, but if you prefer rhythms and arpeggiators I would go with the new Casiotone ct S500 or the cts1000v. Both of these are arranger keyboards and they have my attention currently, as they have the same updated soundchip but I still think the ct s1 has some sounds that are unique to it.

ce clavier a un son magnifique et ça me motive beaucoup à pratiquer.. aussi il est très sobre et élégant.. je lui ai ajouté des notes non collantes en silicone N/B française que vous trouverez ici (recherchez B0FMNMSRJC).. rien à dire de négatif sinon que j’aurais dû l’acheter en premier il y a 4 ans.. il y a plein de vidéos Youtube sur ce modèle et encore plus à voir pour pratiquer.. puisque plusieurs écoles en achètent pour leurs étudiants, c’est tout dire!!

Es un buen piano para principiantes (Como yo), asi como los que tienen algo de experiencia, tiene telcas sensibles, la calidad de sonido Aix es muy buena, tan buena que supera a otros pianos que cuestan mas. Es muy buen piano para que valga 5,000 pesos mx, si lo comparas con los otros sabrás que vale la pena comprar este por su calidad-precio. Les recomiendo muchisimo el pedal para piano para que puedas aprender tambien de éste. Sin embargo, el piano ya tiene la función de teclas sostenidas, presionas "function" y luego la tecla C6 para activarla.
