This product can have a serious impact on the USB market that still survives under the existence of its substitution, Cloud. Its major function is to enable Bluetooth search by connecting it to the USB slot, and pushing Bluetooth button. It basically serves as a bridge. Bluetooth version 4.0 is already widely distributed, and as the technology advances more data transfer will be accommodated. The sickle shaped design is to increase battery space, and to increase impact tolerance so that when the product falls out of a pocket, the USB slot is barely damaged.
