So I bought the Vita Trigger Grips yesterday, even though I figured they'd probably be some cheap plastic garbage that I'd immediately regret buying, and.....they're surprisingly good. They don't add much weight or size to the system, but they feel pretty good, it makes the whole system fit better in my hand. The L and R triggers are really stiff, but they're still better than having them directly on top of the system. Also, it does make the system wider so you have to stretch a little bit farther to reach the touchscreen, but it hasn't been a major problem.
