This is my first keyboard that I bought. So I have no means of comparison to more expensive branded products. I bought it to home to "strum" a bit .... I had no piano lessons, nor should be a clue what chords .... the joy of music is in the foreground are :-) I often times had the opportunity to play a real piano. The first thing I noticed when I had it pulled out of the package was that it is very light for its size. It has a rear connector for a microphone, but unfortunately no headphone connector .... well now, I can live with my husband .... hopefully? ;-) So ... when I turned it on, it made a strange "electrical" noise (as always so whatever sound mag..lol). So I have to press just once without any of the numerous existing buttons, started playing "Für Elise" (I once on a more or less "Children Keyboard" practiced). Mich hats almost backwards gehaun socks off !! The volume was adjusted to the highest setting. Ok first Knöpfchen looking to make quieter .... quickly found ... Volume 1 (scale of 1-12) .... Hokage in low volume ... The sound of the keyboard is the first impression really very realistic. you ..drückt but only a button and listen to the tone, you realize that he is a little "different" sound decays while a bit noisy (why a star deduction). In any case should not be so, as I had been reading from hours of research on the internet. I do not mind anyway! My version of "Für Elise" sounds in any case pretty neat to .... my "beginners ears" gefällts .... :-) And then I have a "Sustain button" found .... the notes sound now after stop any longer. Just a shame that it has to me then the whole song the Sustain function play and not individually then when you need it for certain tones. But it was known that no sustain pedal contain connectable. Never mind .... fun I have anyway! The different tones sound layered partially not very realistic, but it has a riiiiesiges offer. Everything I could not try on the device (I am at Elise deadlocked :-P) but my conclusion is definitely very positive. For someone who wants to use this device as a hobby at home, I would recommend it definitely continue. Especially for those who a lot of bells and whistles around it still need.
