Awful. Run. I have a Mac and apparently no one there could help me resolve the issue of why the back up was not backing up. So frustrating to deal with an online chat person that doesn't even respond. I have asked to cancel and get a refund since this has been going on for 2wks. I just wasted 2 hrs tonight doing an online 'chat' trying to get help on a service that they are supposed to be providing and provided absolutely nothing! We shall see if I get a refund. Doubtful!
