I play for myself and think the piano sounds are accurate for the price. Unfortunately, the noise coming from the keyboard action is very distracting (Even with headphones). It seems like they could have done a much better job of bedding the keys in felt to dampen the clatter.

Has great sound, easy to assemble (about 40 minutes). Looks beautiful.

Impressed by the realistic piano sound: still learning all that it can do

To be fair, it's the only piano I've ever owned. Purchase in December to teach myself how to play. Chose it because of the weighted keys, price, and because it matched my living room decor. I have played it almost every day since purchasing.

This Casio PX 870 has a very realistic sound and feel, and I love playing it. I would prefer if the most important functions were more accessible. To make adjustments to the hall effects and string resonance, for example, you must read the instructions and use the included diagram. Hold the function key, and press the corresponding note to get the effect you like. Other than that, this is a great instrument. Casio did a great job creating a digital piano that plays and feels very much like an acoustic piano. This is a piano. The best sound is the grand piano. I am not into the other tones. Very worth the money for me. I have played Yamaha's, such as the p125 and p515; not to knock them, but I enjoy this more, even though it is not very portable. This is not a gigging instrument. It is for your home.

Bought this new model after months of research deciding over Yamaha, Roland and others. Order from Guitar Center and delivery were great, showed up in a week. Problem is, the keyboard dies/stopped working 2 weeks later. I then had to drive it to a service center, where it has been for nearly 2 months, 4 times the length I actually had it working in my house. The repair center hasn't been able to get the shop manual from Casio as it is so new, and is waiting for parts to just try since they haven't given troubleshooting info to the service centers (getting mailed copies of manuals from Casio?!?!). Worst part? I bought the accidental breakage protection from Guitar center but didn't want to use it on this as I assumed it was something simple. Keep in mind that the piano was plugged in to a surge and battery backed up totally protected outlet so no chance it was power surge or otherwise related. Garbage construction, garbage quality control. Completely unacceptable and while I "planned" in a few years to check out the Grand Hybrids from Casio I wouldn't take one for free and will stick with Yamaha/
