## Customer Reviews

### ⭐⭐⭐⭐⭐ Great design, good quality.
*by A***  on October 30, 2018*

It charges fast, the surface is so smooth, and very lightweight compared to my other battery cases. Easy to slide in and out,I like this case especially how I don't need to remove it to charge.

### ⭐⭐⭐⭐⭐ It has an apple lighting port GREAT! It doesn’t come with a cable (No big deal)
*by S***T on October 15, 2018*

The case is EXACTLY what it says. I like the feel, yes it does add a bit of bulk, but it’s a big battery! I like the raised edge to protect the screen. It feels great, and definitely protective of the Max as I can see. I’m not sure of the battery as of today, but I expect it will be great based on all the proper ratings and certifications it has.

### ⭐ Stopped working after a few weeks
*by S***M on October 18, 2018*

UPDATE: I have now used the case for a few weeks and it no longer works. Case will not charge my phone. Also, when connected to a USB the pass through charging won’t occur either. Only the case gets charged and not the phone. Material quality is very low...more of a plastic type feel. Disappointed and returning to seller.Minimal design and very simple (no logo) which I prefer. Adds weight but that is expected. Press to hold and start charging prevents accidentally activating when picking up or pulling the phone out of your pocket. Full protection of your phone all around but the top portion is a plastic piece that clicks in place. I wish they had made that a magnetic piece as you could use that behind the phone as a stand otherwise when on a desk or flat surface. The magnetic back side I have not tested but it appears to only be directly in the middle and not the entire back....i’ll see how that holds up.The seller is extremely responsive and wants to ensure customer satisfaction which is always a good thing.If you want a case that works as advertised this is a good purchase. I would recommend for XS Max users.
