## Customer Reviews

### ⭐⭐⭐ 







  
  
    A good case, but could be better.
  

*by G***N on Reviewed in the United Kingdom on 25 May 2018*

Pros:1) The case is nice and solid, with a flat back that makes it nice and easy you hold. It has a good weight to it, you know there is a battery in there.2) The material of the case is nice, makes the phone feel very safe and doesn’t stick to the inside of your pocket.3) Although the buttons on the side are thin plastic, they are flush with the case and work much better than I expected.4) The bezel is raised above the level of the screen so gives it great protection if you drop it screen first.5) The power button is big and has a satisfying click to let you know you have pressed it.6) Your phone takes priority over the case if you charge the two at the same time. Total charge time for both, I have found, is about 6 hours.7) The speaker holes are in the perfect place, I don’t get any muffling or sound degradation from them.Cons:1) The description states this case will double my iPhone 7 battery life. I tend to switch the case on at 10% phone battery and I haven’t yet seen a full case charge leave my phone with more than 85%, let alone 100%.2) The charger port is very tight to begin with and you will worry you’re going to break the port/cable the first few times you plug it in.3) You will have to press the power button for longer than 2 seconds to activate it, I usually find about 3-4 seconds and it turns on.4) The clips holding the top of the case on look and feel too thin and I worry every time I have to remove it that one or both clips may snap.Overall a 3/5 performance so far. I will update if anything drastically changes in the near future.

    Didn’t Work With Charger, too Fiddly to get on and off.
  

*by T***0 on Reviewed in the United Kingdom on 15 May 2018*

I wasn’t impressed with this compared with the Wesoo one I had with my older phone. The case was quite angular and felt very chunky. The top section was really hard to take off once fitted to the phone so not easy to get off once on. Also the lighting charger (I tried two) didn’t connect properly so no music and not charging. I sent it back and ordered the Wesoo.

### ⭐⭐⭐ 







  
  
    Great customer service.
  

*by D***S on Reviewed in the United Kingdom on 26 July 2018*

Bought this case on reviews 6-8 weeks ago. It’s a nice snug fit in two parts. Feels good quality and like a similar case I had for iPhone 6, you press a couple of seconds for the backup battery to start charging. Press very briefly, and the charger advises how much juice is left on the case. My issue is that when it starts to charge, if I use the phone at the same time, the charging stops. This is the only reason I have marked the item down on stars. Is it a faulty item, will the sellers let me know?* Update*Contacted supplier. Immediately replaced no questions. Now have a fully working case. Very good customer service and would certainly recommend this item and supplier on basis of my experience.
