Many appreciate the improved grip and protection it offers, along with its ease of use and sleek design. However, some find the case to be bulky and heavy, and a few have noted concerns about its durability. The relatively high price point is also a recurring criticism.

    If your phone is 10% or less and you put this case on the case will be dead by the time you get to 15-20%. So I guess that give you time to get to a charger but I expected it to last longer.

    This case is pretty good. I like the feel and how well it works with the iPhone. Only issue I have is that it only provides about 50% more battery, but I guess that’s about all you can get with these big phones unless you want to carry around a brick.

    I bought this for a great deal (using rewards) and it still wasn’t worth it. I returned it. It only gives you one charge and then you need to charge the case again. So you literally add this heavy case to your phone for just one charge. Meanwhile you can just carry a slim charger pack and get up to 3 charges for a true decent regular price.

    I’m a little disappointed that the battery drains really fast in order to keep my phone charged. It’s only good for 6 hours. I’m thinking to return it.

    This item worked well for about 6 months. Then it quit charging “wireless” now it won’t charge at all. Not a fan. Would have give it 1 star but nobody reads one stars. Also the rubberized coating started peeling off very quickly.

    I ordered this on my way to the store and when I got there I didn’t have some 4 # code. Kid wanted me to drive back home and wait for the code. I live four towns over in Raynham. I had to demand that he take his feet into the store at once and get what I came for. It ended up being the wrong case and another associate who was very nice got Me what I needed.
