It's awful and never seems to take the charge and the battery life is minimal. I would charge it over night and the next day still have nothing. Spend the extra money and get a better case. Also, the button is on the front of the phone and is easily pressed when in your bag or pocket.

i was skeptical based on the various reviews I read about battery phones in general, but Ive been pleasantly surprised. it is a good case and my phone hasn't gone dead since I've gotten it. It provides pretty good protection as well. It does add signifcant bulk on the phone compared to the regular iphone, but its no bigger than some of the other phones out there, or if you had one of those big otter box cases.

The product fits the phone very poorly. I was only able to use it a few times, but it was just too difficult to get the phone in and out of the case. Also, this case is bulkier than other charging cases I have owned previously, so it did not fit in the phone pockets of my purse(s). It was a waste of money for me; I should have bought a different charging case. This one just sits in a drawer now.

GoodI have much more battery lifeBadThe charging cord is different from the typical iPhone 4/4s connection. That means you have to purchase more cords in order to have one for your car and house. The case is very smooth and slippery in texture so it slides all over the car when I drive and raises the risk of it slipping out of hand.

Best purchase ever!! I no longer have to worry about preserving my phone's battery; all I have to do when my battery is running low is hold down the button on the unu for a few seconds and watch my battery recharge to full power within minutes. Easy to plug in at night - charges my phone and the unu together. Love it!!

It's a little thick but that's to be expected because of the storage. I carry mine in my back pocket and don't have any problems. It's nice to hold while texting. Cards stay in place when opened bc of the clip but would like a little more capacity

The product was way off from what it was shown on the website. It was a black case shown in the website and that was the reason I bought it. But when it arrived it was white with a bright orange border. Way too girlish for me..

The design is great but the charger sucks at holding a charge! I charged my phone on standby and it lasted less than a few hours despite what the box claims

It's a really good case. Although the instructions say to charge it at least every three months it has to be charged every night if you use it. If it's fully charged it recharges your phone one full charge. Comes in handy when I am on the go.

It's so nice not having to charge the phone as much and having it run out at the wrong time.
