While dongle porting is their primary function , they are very helpful with various housekeeping chores. So it is nice to have one around.
However, If yours starts making a whining noise it's time to replace her. I suggest upgrading to a newer model frequently as they quickly become obsoluete .
WARNING :Just make sure you do not get one that is too new! You wouldn't want to perform illegal operations
