[Fits Phones Under 6.5 Inches]: Compatible with pedometers and various smartphones under 6.5 inches. [No Harm and No Noise]: Made of plastic material that won't scratch pedometers, smartphones, or your devices. The built-in metal wheel on both sides operates quietly, so you won't be disturbed by noise, even during nighttime use. The support plate with a rubber band can securely hold two phones at once, allowing you to earn steps silently.

[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 to power, and gently start the motion by hand. It will then swing automatically to help increase step count.
