I do not like: the microphone, which absolutely serve no purpose except to be broken. It is a piece of plastic that does not even sound.
I do not like: the scanner. That's really what my daughter is the most disappointed. It does not beep before the bar code (though the same brand and purchased separately), you must press a button on it. It really fake.
Doonc in the end I'm pretty disappointed. For the price, it's pretty good, but I expected better. It is not clear enough what is not working and that is fictitious.
