It is worth its cost price. I’ve been using it since 5 years and no issue is detected. The frequency of getting files currupted is almost negligible. However it is huge and bulky, which makes it little space consuming. Its cap breaks in first 4-5 months and then you have to carry it without the cap. It is water-resistant. Awesome speed of copying files. It supports 3.0 USB port. I didn’t need to do any kind of servicing, so I don’t know about servicing and support stuff!
