Buffalo MiniStation Air 1TB Portable Hard Drive

UPDATE: 7/3/2014 I received the new unit. So far it has been working without any issues. I let the WiFI run all night and here and there I would stream a movie or video clip. So far it has been working great. 3rd time IS a charm I hope. ******** Here's my experience so far... ...This device is a brand new product for Buffalo - so new that I was the very 1st to call Buffalo Tech support about this device. I love the idea of this device - portable hard drive, hot-spot, cell phone charger battery, but I will be on my 3rd one in less than a week. The first device was defective - the hard drive was most likely shot - D.O.A. Could've been the shipping- rough handling maybe?? Amazon was great and the exchange was easy. The second one I got worked. I loaded about 500 Gigs of music and movies on it. I then streamed one movie to an iPad (mini retina) an another movie to an iPhone (5). It was working great, I then started scrubbing the movie timelines to see if there was any lag, well the app or device hung up so I restarted the MiniStation Air. Once re-connected through Wi-Fi with the iOS app I got an error on the iOS app (at the bottom black rectangle/ white letters) of something like "the device is not connected. Check Wi-Fi. The weird thing is that I could wirelessly control the MiniStation except see the files on it. I could power it off from the app or connect it to a Wi-Fi hotspot etc, but not access the files on it. This problem was so jacked up that the Buffalo tech (as helpful as they could be) suggested a return, and being the very first case for this device, I did not want to jack around with trouble shooting. So, let's hope the third time is a charm. I'll update my review after I get that one. I'll give it 1 star for now until I get a MiniStation that actually works (and that's being really nice). What I can say is that Amazon has been great and easy to work with in these exchanges.
