The box was marked 13W as was the shoe, but the actual size as measured with a tape measure was size 15W. Im not sure whats with some of these negative reviews, if you could read you would see they are marketed as light weight. Llegó en excelentes condiciones y es nuevo. The wonderboom 2 has all the great features as the original but with improvements. I work in a hospital so crocs are amazing. I surprised my wife (difficult to do as she has an unnerving ability to guess the contents of every gift) with these comfy moccasins. I was able to use these for a call too, and in that case again the sound was clear and the person on the other end could hear me very clearly. It fell over on me. Yo la uso en mi TV Samsung, ya que el sonido de esta bocina es bastante superior al que viene de fabrica en la propia TV, el emparejamiento es muy sencillo y el volumen se controla desde el propio mando de la TV, un gran punto a favor,, no he sufrido problemas de conexión en los días que lo llevo utilizando, es una buena alternativa si no quieres gastar tanto en una barra de sonidoEn cuanto a la batería me a durado aproximadamente 8-9 horas a un volumen alto y aproximadamente 12 horas de reproducció ------Arrived in 22 hours.
