The little Bluetooth speaker I have received as part of a product test and would like to talk about the product. The speaker will be delivered well protected in a small appealing carton. Supplied located next to the speaker, a micro USB cable, and a small manual. The battery is built with a capacity of 500mAh not just the most powerful and in continuous operation holds a maximum of 3 hours. To charge the Bluetooth speaker, he has to be connected only to any USB port of a computer. A full charge takes about 2 hours. Portable Bluetooth speakers are offered depending on the brand and equipment between 20 500 euros. This model is 25 euros in the lower price segment. The sound quality is surprisingly good, they can not compete with a Bose SoundLink course. Priced at 25 euros but that should also not expect. Processing a quality image and sound, the connection via Bluetooth succeed quickly. Furthermore, the device still has a SD card slot. Overall my Rubik's Cube has very much and can recommend it without hesitation.
