[Fits Phones Under 6.5 Inch]: Compatible with various smartphones under 6.5 inches. [No Harm and No Noise]: Made of plastic material that won't scratch pedometers or smartphones. The metal wheel design on both sides operates quietly, minimizing noise and avoiding disturbance during nighttime use. The rubber band allows the support plate to hold two phones simultaneously, enabling quiet step accumulation. [Supports 2 Phones]: Unlike other models that support only one phone, this device allows two users to share the experience of increasing step counts. [Easy to Install & Basic Function]: The phone swing is powered via USB (cable included). Place your phone on the bracket, secure it with the rubber band, connect the power supply, and gently start it by hand. It will automatically swing to increase step count.
