Reviews for Mophie Juice Pack Plus Battery Case for iPhone 4S/4

I've had this case/pack for about 14 months, taken it everywhere (hiking, biking, travelling), dropped it on my driveway a couple of times, and it's flown off the seat of my car onto the floor many times and it still works great. There's minor cosmetic wear to the plastic, and it's slightly more finicky about which USB cables it "likes" but that's about it. Regarding mini-USB cables, they do tend to wear out and get a bit loose. I have a lot of mini-USB devices and the effect is more noticeable on some devices than others, but nothing that a (cheap) new cable won't rectify. The result can be looseness in the connection, or even, with Mophie in my case, an inability to charge the phone (though the Mophie battery charges fine) while plugged in. Using a newer cable rectified these issues. I love my Mophie, even though it's a bit heavy. It's saved my bacon more than once.
