This is a Pioneer DJ DJ controller compatible with Serato DJ Pro. I used it about once a month, so there are minor scratches and scuffs. There are no operational problems. The faders are not loose. It works normally. Please check the photos. Please research the compatible PC versions yourself. As a bonus, a SR2-specific decksaver and an SR2-specific bag (one side of the zipper is broken) are included. I will ship it with the bag. These are just bonuses, so I will not accept any claims regarding the above two items. If you have any other questions, please ask. - Brand: Pioneer DJ - Software: Serato - Controller Type: DJ Controller - LED Lights: Colorful LED Backlights - Platter Size: Large Platters - Connection Terminals: USB Connection - Effect Control: Equipped with Effect Knobs - Button Layout: Intuitive Button Layout - Mixer Function: Built-in Mixer Function - Size: Compact Design Pioneer Dj DDJ-SR2
