Was worried about the bottom being covered but was happy it charges the phone through the case The indicator lights are beautiful and it feels solid You can toggle it on and off, enabling the charging function only when it's needed

This product is a joke. Holds a charge for about an hour then dies. Complete waste of 50$ that I want back.

It stopped working after only a couple of weeks. I have not reached out to manufacturer yet but I am planning on doing that today. While it worked it was awesome!

It's not as protective as I wanted, but nonetheless, it has protected my phone when I dropped it.

I love this case! It kept my phone charge all day at Disney World, where I was taking pictures and using the DW app. When we left the park at 10:30 pm the phone had a 94% charge!

Material is very cheap and you cannot use the same iPhone charger to charge the case, when other brand cases you can.

It only last for 1 recharge for my iPhone and I thought I would get at least 2 full charges out of the battery back up.
