[Fit for Phones Under 6.5inch]: Suitable for pedometers and various smartphones under 6.5 inches. [No Harm and No Noise]: Plastic material does not scratch pedometers, smartphones, or your devices. With a metal wheel design on both sides, it operates quietly and will not create noise that could disturb sleep when operating at night. It can hold two phones on the support plate using the rubber band simultaneously, allowing you to earn steps quietly.

Place your phone on the bracket frame, secure it with the rubber band, connect the power supply, and gently start it by hand. It will swing automatically to help increase step count.
