It was impossible to normally use this product. Indeed, despite all efforts, it was not possible to operate normally more than two buttons. All other blocked each time, never returning to their original position when released, thus making it impossible to remove the paper without tearing it. Believing to unlock buttons, any attempts to remedy were unsuccessful, and having led inevitably to mark plastic. What the rest prevented us from returning the defective product. In short, totally dissatisfied with the product no longer useless. With the consequence for us to have to buy another toy for our little son. Total disappointment.
