I just have a few questions to those who have bought one. 1) I'm thinking of getting the battery+dock, as I extensively use the stock dock when charging my 3DS, but after reading reviews online, people suggest not to buy the combo and just get the battery. Has anyone had problems with the dock, or believes the dock isn't worth it? 2) I have a DSTWO, and I hear that with the PP+, it creates a problem with that flashcard because the battery pushes up against the card slot. Does it really make a problem with the battery (in terms of inserting and removing the card)?
