Rokform RokBed v3 Samsung Galaxy S4 Protective Case with Universal Twist Lock Car Mount - White - Durable Phone Case for Secure Mounting in Car, Home, or Office

I purchased this case exclusively because they make a bicycle mount and to use their mount, I had to purchase either their case, or their universal mount. I have been using the Otter Box Defender (think big, bulky case) because I inevitably drop, toss, and occasionally throw my phone. I also toss my phone in my purse with my keys and various other items which tend to scratch everything.I thought about purchasing the universal mount and installing it on my Otter Box (and I still might do that), but I figured I'd give their case a try first.I'm not entirely sold on the case, it's VERY slippery compared to my otter box, and I've already dropped it just because it was slippery, where as my otter box was "grippy" in comparison. The case seems durable, it's not bulky, and doesn't seem to weigh much. The hole in the back for mounting purposes isn't a problem for me, (especially since that's why I bought it!) but my boyfriend pointed out that it'll collect lint, paper, and other bits like crazy.I was disappointed that it didn't come with a magnet, but received the magnet insert with the bicycle mount I concurrently ordered. *The magnet has to be the single best part about this case.* I never thought about how convenient it would be to stick my phone to my refrigerator while I'm cooking (eye level for recipes and music), or even in the bathroom. Also, all of my office equipment is metal from the 80's so I can stick it to my desk, my filing cabinet, etc. It's fantastic.Bottom line, the case is acceptable. I only bought the case to use with their bicycle mount (which I'm pleased with). I don't dislike the case, but I'm not in love with it either. If I had to do it all over again, I would probably buy the universal mount, (plus the magnet!!!) and install it on my otter box.
