The design is original and functional (the little light refraction in the "radiator" had its effect) but the messy side seems a little inevitable given the gap between the speaker and grille, to see in the future if the sand does not hinder the closing of the device aileur very friendly (even for someone of cautious).
A defect: The package, virtually impossible to open without trying at least 20 times and the USB cable and manual stuck in the double bottom (should say) that tears of fear are really annoying to open, in short it is not an iPhone or beats package;)
However going to know why there is no technical elements in the product ... I will clarify key:
-Power: 2.5 W
-signal:> 86 dB
-Battery: 4 / 5H bluetooth (even I have not checked but you can climb up some DAfter 7am) -Charge: 3 / 4H
-Size: 70X53mm (not 10x8cm - 'even the package is not this size)
-Range: 10m
Hoping to have convinced you of the quality of product (apart from the package) personally I'm a fan;)
