Very good hunting @giovaabbatichio, this product is great to listen to music outdoors. Here I will leave you my comments on Pros and Cons.

Pros:

• It has a sophisticated design perfect for any house, also has unmatched features that make it much more than a simple speaker.
• After having your full charge lasts up to 8 hours with the energy stored, perfect to continue the party even after the sun went down.
• You can link your phone via BlueTooh and place your PlayList without having to connect your phone to KeyStone.

Cons:

• Your advertising campaign shows these speakers in the home, where it is impossible to charge them by sunlight.
• Its launch price is somewhat high.
