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.

I own a top flight acoustic piano and professional digital keyboards. I searched everywhere for a portable, super light-weight keyboard that I could carry on when flying/traveling to use for practicing and composition. The Casio CT-S1 fits the bill well, with a few very minor nits.

This keyboard weighs in at less than 10 lbs. yet is very well built and 'feels' sturdy and solid. It's physically impossible to have weighted or semi-weighted keys on a 10 pound instrument, but the key bed is otherwise very good. The keys are nearly full-size, have a matte finish and a good touch sensitive response.

The body of the keyboard is well constructed and does not feel fragile. The 'retro', minimalist look of the instrument with the cloth covered panel across the top is easy on the eyes. There is a built-in handle which allows carrying around your house or hotel with ease. It comes with a external power supply, but also runs on batteries. I sprung for a set of AA rechargeable batteries, worth the investment. Nit #1: You'll need to purchase a sustain pedal - not included.

There is a very good and wide range of sounds, most important of which are decent acoustic piano, electric piano and organ voices. A nice feature is a set of physical buttons and a volume knob across the front panel. There are dozens of additional sound and tone controls accessible via the function button and the piano keys. Nit #2: I would like to have dedicated buttons for the most used functions: transpose, octave shift and reverb.

The built-in speakers are very serviceable. There are 1/8" inch stereo IN and stereo OUT connectors, so I carry a couple of 1/8" stereo patch cables for connecting my Klipsch Groove bluetooth speaker (sounds great), tablets, phone, etc. The USB MIDI interface is ideal for for writing or transcribing music.

Nit #3: The Casio case for this instrument, when available, has an awkward design (load from the end ??), and has questionable padding for travel. Casio would do well to make available a decent, well fitting, padded case - even at half the cost of the keyboard, it would be worth it. I scoured the retail world for days to found a good quality, padded, but otherwise snug fitting case for airline carry on, but a case designed for this unit would be better.

This instrument is an excellent value.

5.0 out of 5 stars I compared all the similar keyboards on Amazon

I bought this after comparing as many keyboards as I could find on Amazon.
My 4yo daughter has taken an interest in piano and this keyboard actually works great for beginners or advanced musicians.

This Casio is the whole package. There are 3 sensitivities for key response depending on how hard you stroke it, there are 61 sounds that all sound unique and inspiring, there's a customizable built in metronome, a one-touch button for recording your playing then giving the playback with another button press, there's a surround button to expand the "size" of the sound (the speakers sound great on this), outputs for headphones and external sound, and you can connect different types of inputs to play along with a song or learning app.

To be honest, I probably would have gladly paid closer to $300 for this unit. Instead, I purchased the Pyle keyboard stand (fantastic, sturdy unit with plenty of amenities), and a sustain pedal with the "extra money" leftover from what I valued the keyboard at.

Any units in Amazon that are cheaper than this one have drawbacks that this Casio doesn't have. Essentially they are more "toys" than an instrument. This Casio is an entry level "hobby" unit that is useful for recording too.

I've been a musician since I was a child, so I have somewhat of a good idea for what makes good sound.
I can't wait to record with this keyboard!

I love the sound that this keyboard makes. There’s a plethora of presets, and each one sounds lovely to me. The has a great feel, and it’s comfy enough to simply rest on your lap if you don’t have a stand or much space to set up your own area. The sound quality alone is enough to make someone like me get a lot more serious about learning the keyboard. I would truly recommend this keyboard. And the red is devilishly handsome in person as well.
