Works great and lets me not have to charge my iPhone in the middle of the day. If I plug my iPhone in every night and get a full charge (battery pack and iPhone) I still have plenty of battery throughout the day and night. Pack does constantly charge the phone so I am not sure if that will effect the batteries ability to charge long term on my phone. Had it for over a year and so far no damage to the phone’s battery. Setup is easy. Snap the phone into the plug at the bottom of the case and snap it into the rest of the case and that’s it. Battery pack will appear on your phone as well as the iPhone internal battery letting you know how much charge each has. Once in a while it gets a glitch where it starts using the charge from the phone first instead of the pack. Easy fix is to pop the phone out of the case for a few seconds and then snap it back in. Works great after that. Case protects the phone very well. I have dropped it a few times with no damage so far. I’m sure there are tougher protective cases but they don’t have a built in battery pack so this is definitely worth it. A bit pricey but worth it.

Great case with little bit of weight, but is worth it for a heavy iPhone user, extra battery! Been using it for more that 5 months so far!

Love this case. It’s different from mophie or ones that turn on with a button but I’m getting use to it. A lil heavy but all battery cases are.

Shipping was fast, the case was well packaged, I go 2 1/2 days without needing to charge my phone thanks to this case , highly recommend it

It works as intended last pretty good amount of time. Only complain I have is that the smooth texture has rubbed off the edges making it shiny
