    "Love it...5 stars...great charging case...This case does add a bit of weight but not much doesn't feel bulky plus it does protect your phone from drops just I wouldn't use this case if you really drop the phone a lot because I'm pretty sure your gonna notice a lot of scuff marks on the case and when you hold the phone in the hand it won't feel good holding the scuffs but over all that I'm satified with the case I give it 2 thumbs up."

    "5 stars...It's ok...This is a good reliable charging case....We're not really sure how much protection this case provides, but just based on how it looks and feels, it appears to give a fairly significant layer of security against typical bumps, drops, etc., but I wouldn't go so far as to say it's as good as a high end case designed solely and specifically for the purpose of protection."
