A truly awesome Keyboard to have. Though I am a beginner in this instrument, still I would like to recommend others to go with this keyboard for following reason:
1. Grand Piano sound is really Genuine. I have heard some of the other Piano sound like CASIO CTK 7300IN, KORG, YAMAHA PSR i425 & PSR i455. Undoubtedly PSR e453 sounds more realistic than others.
2. PSR e453 contains 758 voices which includes the quality sound of Strings,Brass,Flute,Harmonica,Trumpet,Sax and many others. You will experience that the sounds are quite real to a great extent within this range.
3. There are enormous styles & patterns available in this keyboard to accompany with your own tunes.
4. You will get a good number of options to record your tunes/songs along with your chords & other patterns as this keyboard provides 10 User track sections and each section can be recorded with 6 different banks.
5. Speaker are great in-built quality. There are no cracked sound even if you play with its highest master volume.
6. The most important thing - PSR e453 has 8 bank to register the voices where each bank has 4 sub banks. That means total 8*4 = 32 sound registration is possible in this keyboard which is quite good enough to perform on live stage.
7. This keyboard has the USB to host port through which you can import or export the tunes to/from the keyboard.
