Only worthwhile for the L2 and R2 trigger grips.
As this has been said before, I'll keep this short. The armor is pointless, and actually inhibits the use of the start and select buttons. As my controllers are protected by silicone skins, I bought two of these strictly for the L2 and R2 trigger grips. They deliver as advertised. Don't bother here if you can find similar trigger grips elsewhere.

Not worth the money
Firstly, the armor is a waste of time and i have actually thrown it away. It hinders access to the select and start buttons.

Basically, you are paying $10 for a single piece of plastic on the right R2 trigger. (the one on the left isn't even necessary).

If u don't mind the price though, the trigger is a big help in first person shooters.

i keep hoping someone will put out a better controller as i am keen on another but i don't like the present controller

Nice little accessory
I would've paid $10 for the triggers alone! The armor is an extra bonus for me and makes this purchase a no-brainer. If you're into racing games and your fingers continually slip off the L2 R2 triggers, then get these.
I also purchased the 4 pack skins from Eforcity and the armor fits great on top of that. Worth every penny!

Hardware Controller Armor
Do not buy. Piece of junk. The buttons are the only thing that is decent.

Improvement but not perfect..
This is an attempt to fix what Sony screwed up and had a chance to fix with the Dualshock 3 but chose not to. The trigger extensions work pretty well..they keep your fingers from slipping off but still don't supply the same kind of "feel" you get with the nearly perfect 360 controller triggers. The "armor" thing is pretty useless and tacky looking...I don't use that at all.
