Not trying to threadcrap, but I can't express how unhappy I am with that change. These hard click switches are such ass compared to the old user-servicable membrane. Both my B button and R button don't seem to register for about 20% of the button presses and there's nothing I can do about it. If it's the old style membrane I just would have been able to dab it with some contact cleaner and presto, your buttons are good for another 2 years, but they had to implement this housed hermetically sealed switch which apparently still has some crap going on in it because it simply doesn't work properly.

Either way, that's a great price on the 3DS XL. Hope it sells for you but I guess i'm waiting for the refresh and crossing my fingers for better button engineering. GLWS
