Despite all these advantages, this flexible keyboard has disadvantages. The first is that of course you will not find the touch of a piano keyboard. So no need to imagine start learning about this product. The second is the quality of the piano, which remains quite metallic. However, one can not ask a keyboard within 50 the quality of a digital keyboard to 1000!
It is also unfortunate that the device is supplied with an AC adapter that does not work in France. So instead of having 2-way power supply, there remains only the batteries (4 standard AA batteries).
I still love this piano because it's a great toy for children. My daughters never stop wanting to touch my piano and with this flexible keyboard they can have fun without risk! When we look at the price of musical toys for children, the price / quality ratio is really top.
Besides the diversity of sounds allows children to create many combinations (more or less harmonious I grant you). A neighborhood watch is to keep as it is not designed to be a toy.
In conclusion, I recommend this product, not to practice the piano but just having fun!
