Got my Otterbox today for my One V and I like it. At first I thought the fit of the inner silicone layer was a bit off on top, but after fitting it I realized it is cut that way allow the notification LED to be seen from both front and top views, as well as to avoid covering the speaker.
It's a tight fit and will give excellent protection as always, though I must say the One V is pretty tough on its own. Mine took a spill to the floor, doing some rough tumbling along the way. Not a scratch, no issues at all... But I feel alot better about it with an Otterbox on there.
It doesn't add much bulk to the phone, and it's still very light. It de-accents the chin a bit, but it's still there. All buttons are easily accessible, and the ports are covered with silicone doors.
I am not too impressed with the screen protector and will probably replace it with a Skinomi TechSkin. Of course since the One V has Gorilla Glass it's probably not really necessary... But overall I am happy with the Commuter.
