I have not been completely satisfied. I have had to have my Time Capsule "repaired" twice at the Genius Bar when it simply quit working. In both cases 10 days passed before I was alerted that there had been no downloads in so many days. I fear that I must say this product is unreliable. For the price, one expects far more. I would not recommend. There are other products far less expensive that do the job.
I can't count how many times the wireless Internet quits and I have to hit the reset button on the back. This is the only problem I have with this time capsule. I'd rate it 5 stars but the wifi stops working all the time! I tried to return the thing but apple said it was out of the return range. I'm an apple fanatic don't get me wrong but I'm in the process of switching back to a regular wireless router and USB external hard drive for back up and storing files.
