I've had this case for a couple of weeks now and I find it very functional. I like having a waist clip for my phones. This case has that and is not too bulky feeling and does an ex job of protecting my phone e from drops, etc.

Great protection

I love the case and protection it provides. The drawback is the lens protection! There are so many and such a big area! I bought the ESR tempered glass....thankful for the addition!

Love It

Love the case. Feels very comfortable to grip. Was a little difficult at first to install to phone but once on loved it. The plastic holster was a little awkward at first but getting used to it. Not sure how secure it will be over time. Dropped the phone once with no problem. I would recommend it.

Great fit not bulky size
