In the name of God, the Most Gracious, the Most Merciful. The device is new, used for a very short period. The device works with mobile, laptop, and computer. It comes with a discount coupon in the app. A professional device - hobbyists and professionals alike. It is very suitable for those who want to start a DJ project. Its price when I bought it was 1499. Asking for 1000. Ha'il only. Whoever is serious can come see it before buying, with a one-day warranty. Today it reached 850 and the limit is 1000.
