I was using this until recently, but I switched to a different smart band. Since this one still works, I'd like to pass it on to someone else so they can use it. [Product Details] This is a used smart band, an activity tracker with IP67 dust and water resistance, and a battery life of approximately 20 days. The included wristband is used and has scratches, so it is not included with the product. However, I will include two unused wristbands. - Model: Mi Smart Band 4 - Color: Black - Dust and Water Resistance: IP67 - Accessories: Charging cable, Instruction manual - Battery Life: Approximately 20 days - Operation Check: Confirmed, no problems - Extras: 2 wristbands, 2 screen protectors - Contents: Items shown in the photos Thank you for looking.
