I bought the adapter to connect my Macbook at work with the external monitor. After just one week began the adapter in gaining access when placing the cable into the enclosure! After about 2 weeks, the adapter was unusable because a loose connection in the cable meant that the image continually disappeared! In addition, then is ultimately still the plastic case fell apart (see picture customer in product description). Be honest. Because I'll buy but rather the overpriced original adapter from Apple and have peace, rather than me every month to buy a new Hama!
