Easy to use. The best sound is as it is in equilibrium, so do not put it in the end table. Warning it comes with a nice charger with USB output 3 (Pure Power), the connection is Mini USB, the middle one is for the speaker, but it is 5 amps, so do not cherger with this as your USB port is 5 to 10 times the traditional amperage. With a usual charger Leveque borne by the bridge should be slower than expected. The presentation is great, in short, a gift to do.
