  • It’s good but it could be less fragile
Style: FX991 Capacity: 2TB
It works , but the thing is that the item is real fragile and you can’t push too hard , it opened up a little and I thought it was not going to work , but it does. Only thing , the little screw that came with it , it’s so small that it wouldn’t stay put , so I had to use tape.
