Negative side, it is always a little larger than some protections more "light". For comparison I had One clear box before which is very refined and fully leaves the design of the One who speak but poorly protects my taste .. It's all about compromise, or design protection remains for me the best compromise. A friend also noted that plastic is more flexible in terms of the length of the phone (at the buttons) and moves a bit, the protection does not remain "stuck" perfectly. Personally it's not at all embarrassing for me and it is quite logical protection but being flexible to take into account in your choice.
