The Startone keyboard was bought as a beginner set alongside with stand and headphones.
It delivers what you need when you are starting to play on piano. Velocity sensitive keys are huge advantage, even more in this price range.
USB MIDI is good to have, however I didn't use it yet.
Pitch bend looks flimsy, however it works and gives me possibility to use it.
Piano is loud enough for exercise in the room. The quality of the speakers is not bad, but I wouldn't use them for anything else then own practice.
One of the biggest advantage is the graphical display and all the options of set up that piano gives you.
I didn't find many cons of this product, in this price point its really hard to beat it. However the construction of piano could be improved, as the material look and feels cheap. This doesn't include the keys which are fine.
If you want to start learning piano or want one just for fun, I think Startone is a good choice.
