Prior to the Symmetry, I had a Commuter for just under two years. I thought the Commuter was just a little thicker than necessary, and the covers over the headphone and power jacks could get annoying.
When I heard about the Symmetry, I saw that it addressed both of my issues with the Commuter - thin and no covers over the ports.
So, I have already managed to drop my phone with the Symmetry several times at home and in a parking lot, and I am seeing no damage. Access to the power and headphone jacks without covers is very welcome.
One thing I like about the size of the iPhone 5 series is that it fits in my back pocket, versus many of the HTC and Samsung phones that are too large. Even though the Symmetry is just slightly thinner than a Commuter, it fits even better in to my back pocket.
Another benefit over the Commuter is that the Symmetry is simpler to install around the phone, while the Commuter is a multi-step process. Obviously not a big deal, but definitely an improvement.
I did not receive any screen cover with this case. That was a surprise, because I would swear I did receive a screen cover with the Commuter. I don't see any product information that would indicate you should receive a screen cover, so my fail.
This is not the cheapest cover on the market, but I believe you get a great product at a fair price. I would definitely buy this again, if need be, and would recommend it to anyone that asks.
Pros: High quality, Durable, easy access to jacks, very thin
