Anyone have experience with Skinomi/BodyGuardz skins?

[harryg27]

I'm thinking about getting one of the carbon fiber skins from either Skinomi or BodyGuardz. I currently have an OtterBox Commuter and suffer from echo issues due to the bulk of the case. Is one brand particularly higher quality than the other? Thanks!
