Wonderful! 
2006-08-16
I love this piano. It has a beautiful, real sounding tone, and the keys are weighted perfectly. It was a great value! It doesn't have a lot of features (some of the keyboards now days are more like computers than instruments) which is part of the reason I wanted it. I just wanted a piano - and this is extremely close to the real thing at a fraction of the price.
Is this a piano?... Excellent Keyboard 
2006-07-09
Positives: If weighted keys are important to you, this is an excellent step up from a keyboard without weighted keys (especially if you originally learned how to play on a real piano like myself). I live in a small dorm room and this piano tucks neatly into the corner having a width of less than a foot. The included sustain pedal also works very well. This piano comes with a wonderful music book with the music for 29 classic piano songs and some fun songs to play or listen to. These songs are already built in to the piano and sound like they were recorded by a real musician. It is wonderful to be able to see the beat displayed and be able to slow or speed the tempo of these songs in order to learn them and play along with them. The easily recognizable songs are Beethoven's Fur Elise, Moonlight Sonata, Bach's Menuet, Debussy's Arabesque, and Satie's Gymnopedies. Also the demos but not sheet music are provided for Over the Rainbow, Let it be, Happy Birthday, and a few other modern songs. My favorite out of them all and a real challenge is Chopin's Fantaise-Impromptu.
Negatives: It is a step down with features though as this keyboard only has a few. There are only 8 tones, but the grand piano tone, which is really the only necessary one, is excellent. Many of the features are utilized by the control key and depressing different notes on the keyboard to change things like Piano Key (F# to C to F), keyboard touch (Off, weak, normal, strong), chord mode, reverb type and chorus type. There is a handy quick quide sheet for this and is not too big of a deal. The only major negative I would give this piano is the speakers which are not quite powerful enough and don't produce too great of a sound. They are sufficient though. To make up for that the keyboard can easily be plugged into any speakers through the convenience of having two headphone jacks.
The biggest positive which was not mentioned above is the price which easily justifies all the negatives making this a superb value. If you need a small, 88-key, piano-like keyboard for the lowest price, this is the product you are looking for.
Enjoy having an acoustic piano without the weight and a fraction of the price.

I just had this piano a week or so and me (who doesnt play) and my wife (grade 1 level) enjoys it so much. We bought it for our daugter (10 yrs old) to see if she gets interested in playing but now she can't even use it cause she can't get her turn on it. hahaha.
Pros:
The size is so slim (depth) that it won't take up much space in your house. And so light aslo. We live on a 2 story house and I wouldn't even consider getting an acoustic piano and lift it to the 2nd floor.
Complete standard size 88 keys w/c are weighted, to make it feel like a real piano when keys are pressed. Unlike those keyboards (some w/light up keys w/c is not a good idea for learning).
It's electronic so they manage to put a metronome to keep your notes even on a specified beat speed. This is very important for any beggining musician. Develop your sense of timing and rythm so always play with a metronome or a beat. We tend to speed up on the notes we know and this will make our playing speed inconsistent w/ the rest of the notes or chords. (I know because I've been playing guitar for 15 yrs)
The best part and me and my wife always is fascinated is it has earphones so we can play anytime in the late of night or practice, practice and practice those repetative boring songs and annoying - to - the- rest excercises w/o anyone complaining. It actaully has two earphone plugs so you can bore your better half if you want to. Beat that acoustic piano!
It has a few (forgot how many) built in songs and we love to play them (classical) when relaxing. It also has the beatles song "Let it Be" which is my first goal to learn. My wife is learning Fur Elise and we can always listen to these songs right from the Casio PX-100 to learn them. (BTW it comes with music sheets with these classical songs)
It has a few other musical instrument sounds like stings plus a few more. Not as much as the toy keyboards but better than what an acoustic piano can produce. We only use mostly piano sounds though. And it sound like real acoustic piano.
Cons:
Wood stand looks cheap and is not really wood but particle board with formica. I prefer to make new stand made of wood and stain them to our liking. They are very simple to replicate, it seems.
I hope it has an LCD to tell you the speed of the metronome.
If you like changing settings it's difficult to do w/o the quick start page because you have to press CTRL plus certain keys on the keyboard w/c are not labeled.
Uses electricity, so can't be used on power outage. But how often does that happen, I know.
Conclusion:
This is a better alternative to an acoustic piano in most /all aspects. I think Yamaha Digital pianos and the more expensive ones recreates a better acoustic sounding piano but it's a matter of preference. And not all Acoustic pianos create the same sound right. But for the price $399 at Amazon w/o TAX and free shipping, the cons would not even matter. We are able to enjoy playing the piano at home w/o spending too much. Learning is not boring anymore unlike when I tried before.
Nice!

I only wanted a basic piano (no special features) but good quality and as close to a real piano as possible. I read the reviews and bought this over the 500 or other models and am pleased. The 'casio' pedals aren't very big but they do the job. The casio stand and pedals would work best on tile or some hard flooring (I only have carpet in my appartment). I only mark this 4 stars because I don't have any other keyboards to compare to.
Wow! It's a great digital piano.

It's a great digital piano. Though it does not have more bells and whistles, it serves the purpose. My seven year daughter uses this piano. She liked that. Her piano teacher is savvy about the pianos. She also liked the quality of this piano. It's a great product.
Excellent value for money

I was looking for a weighted midi keyboard, not necessarily with its own sound generation, and it was hard finding something at the $400-500 mark that felt good. Well, colour me surprised that the Casio has a very realistic feel, and it even sounds good.
The built-in speakers are not all that big, so they're fine for practicing on your own, but probably won't hold up if you're playing together with more than, oh, say a flute.
Also, if you're using this as a midi controler, make sure your host has velocity scaling, because I can't get velocities over 110 or so out of this thing, no matter how hard I hammer.
Also also, the pedal that comes with it is a simple affair. If you buy a better pedal make sure it has the right behaviour or is switchable, because the pedal that I have will sustain when *not* pressed, and damp when pressed. There doesn't seem to be a software setting to reverse that.
I'm ready to buy it but need questions answered PLEASE

OK until it broke

I bought a Casio PX-110 as a Christmas present for my 15 year old grandson who was learing to play the piano. After 10 months of careful use a single key stopped functioning correctly. I had the credit card receipt for the purchase, but not the original sales receipt. I sent Casio the paperwork I had plus a notarized letter on the circumstances of the purchase, per their request. Casio says they didn't receive the documents and would not repair it under warranty. Twice the Casio repair center said they would call me back and didn't. They wanted to charge me $257.00 to repair one key, which I declined to do, fearing another key would break, and bought a Yamaha keyboard instead. I feel that it is a serious quality problem when a keyboard breaks in less than a year, and a design problem when it costs over $250 to reair a simple problem.
Great Product

This is a xmas present for my son. He will be very pleased with it.
Very Pleased

I am very happy with this product. It fits easily in the corner of my tiny dorm room and stores easily under my bed. The key action is great, and the sound is high quality. The "split" feature is perfect for jazz pianists; you can walk the bass guitar with your left hand, and play with your right. The pedal is a little flimsy, but serves it's purpose.
This piano is easy to move, easy to store, and fun to play. (not to mention it's VERY cheap)
