I love buying solid, especially for this kind of product that we walk all the time, I used. It weighs its weight. We see / immediately feels very good. The removable connector is really great. We are dealing with a product that will last over time.
It is extremely fast, is stunning. 2200 music files (20 GB) copied in less than 5 minutes. Some are expensive, I think it is worth it price. The quality is paid.
