Nice design, fit could be better Review by 1&Done
poor phone fit in battery case, the phone moves side to side inside the case at the top and also slightly changes the registration of the camera, flash and sensor on the back of the phone. The external battery takes quite a long time to charge per the led's on the back. The battery continually charges the cellphone even when the cellphone battery is full and the cellphone says to disconnect the charger. (Posted on 7/26/2014)
Emergency Backup Battery Review by Deborah C. White
I purchased this battery case with the intention of using it as my new Galaxy S3 case.

Here is why I could not do that:
1. There is no power switch. The battery constantly charges your phone. It teeters on and off at 100% phone charge.
2. The case gets very hot when charging (which is constant). I couldn't even hold it when it got that hot.
3. I lost a full charge while browsing with 3G/ 4G speeds within 2 hours. It takes over 3 to charge fully.

I didn't mind the extra depth or length it gave to the phone. It fit on the phone fine.

The case instructions said it came with a charging cable but the box contents says it does not. The case instructions also reference both the Galaxy S3 and iPhone as the type of Battery Case purchase.

I would recommend this case as an emergency battery case, not an everyday case. (Posted on 7/25/2014)
Great value! Review by JIM KREY J
Not quite double like advertised and there is play side to side and no lip to absorb impact if dropped face first. But for (price) and a third more battery life approximately I can't complain. (Posted on 7/22/2014)
Significantly Increases Battery Life, A Lot Of Drawbacks Review by Jeneen
- Does seem to double the phone battery life. I can now go all day without charging.
- Does add bit of bit of depth, height, and weight to the phone, but not significantly and I personally like the added dimensions.

- I ordered 2 and one was dead after a day's use. The case seemed to charge, but would not charge the phone. Since I bought from another retailer, I had to pay to ship it back to the manufacturer.
- Case is as slippery as a bar of soap. I added bathtub tread stickers to the back to help.
- The phone is not a tight fit - it wiggles a bit in the case.
- Not a protective case. It fell from 2 feet onto carpet and I had to snap a separated piece back into place. I sense that if it falls in any position other than straight on it's back, there will be damage to the phone.
- Takes about 4-6 hours to charge fully. (Posted on 7/22/2014)
