Do not buy from BESTNAVY TECH Store. Sent me a bad DVD drive. Wanted me to pull up on the sides to fix it. Sent videos and pictures to dispute. Like many reviewers have already stated, the dispute always goes to the seller. They said I didn't have proof (even though the videos and pictures show a bad drive). This model isn't sustainable and eventually people will catch on. When you think you're saving money, you're not. Especially after you loose $100 and then just have to buy it from a reputable place that stands behind their products...like Amazon. Never again from aliexpress. Until they clean up their act, be prepared to kiss your money goodbye.
