Average quality, empty batteries back to review

The products themselves are average, the English lyrics on the remote are incomprehensible for an adult, so for a child, I can not imagine. During my first command, the remote did not work, so back (in 2 weeks, so it had to be fast delivery), and there are batteries that are not working. I'm pretty outraged lack of professionalism of some sellers. For 30 euros, we would have at least products that work.
Apart from this, the products are colored and noises / sounds are attractive to children.
