Inserting the batteries, switch, wait until it beeps, phone to Bluetooth and off you go. The service is really super easy. For me, the speaker also has the four periods actually managed easily.
The sound is really surprisingly good at low volume, but clatters in some places a little when you turn sharply. However, no hi-fi will expect quality for under 30 euros probably. Clean for the sound there would have been of me only four stars, but for the price / performance ratio, there is the fifth to.
I really like the design in its simplicity. In addition, the Red fits perfectly with my tablet: D
The package includes the battery, a USB charging cable and an audio cable.
For me, a good buy.
