Used for about two weeks. I bought two colors, white and this one, previously, and kept them for my collection. I only used it for 2-3 hours a day, so I think the condition is very good. There are some minor scratches on the outer box, so please refrain from purchasing if you are concerned. - Model Name: Viper v3 PRO - Color: Black - Connection Type: Wireless - Included Items: Cable, Package - Sensor Type: Optical Sensor
