The size of the keyboard is hard and I do not want to drag in a classroom. For a smaller model would be better suited. I bought a keyboard stand with double tubes for 35, since the keyboard should rest securely with its size. That works perfectly.
The music stand is with me as an accountant for my textbook. A clip ensures that the pages do not turn the page on its own.
The manual is very detailed and explains all the functions very precisely. However, as a beginner I need them to nothing. Adjust the sound, I get out without a manual. I like to try out.
My Conclusion:
The Yamaha PSR-E433 is an ideal keyboard for beginners and obviously want to learn and advanced indoors playing the keyboard. For carrying around, it is too bulky. The sound is very real and makes the good speakers of the keyboard right mood. You can play many instruments extremely. Just a great unit.
