Hi! We live in a hurricane zone. I've heard good things about these products; so I ordered a T320 battery pack online. The company was actually hesitant and called me at home! The rep wanted to verify that I am who I am, and not using a compromised credit card! Hahaha! Awesome. Then she said that she wouldn't bother me anymore about it. Got it home and tried it out; worked great! I then ordered another T320 and put it into the hurricane closet as well. Of course it has limitations; but serves the basics. Now I just ordered the new T600; can hardly wait to see what it can do! Very happy customer
