Fabulous & easy!

I purchased this on the recommendation of a sales Rep @ Best Buy & am so glad I did! It is simple to use & compact. I have a Samsung Galaxy SII phone & the juice pack holds enough charge to recharge my phone TWICE! I bought it 10 days ago & have already used it several times to recharge my phone when I didn't have access to a power source. I even used it in my pocket one time. That was a bit bulky but I wanted to test the convenience if I needed to charge on the go. Highly recommend!
