sorry non sky3ds user but just a point that should be made ( i would imagine)
but i know there has been stores of buttons falling off or saves being deleted, but its worth mentioning that im sure buttons falling off would likely be down to how hard someone pushes the button, i know some people can be very heavy handed so one or two people mashing the button in and breaking it is probably well within the range of normal heavy handed user figures
and the corrupting saves could also be down to people using poor quality/fake micro SD cards, many average consumers just buy whatever is cheapest, the amount of "why is my games showing up as white squares" on gateway cards is testament to that,
in all i think its been kind of long enough to get a general idea of if there was any major flaws or problems with sky3ds, all in all its mostly all good from what i have hear,if there was any major issues there would be many more threads with people having corrupt saves/broken buttons
on post i did read said that the sky3ds seems to get stuck slightly in the n3ds, maybe the user had a slightly off center card slot or something, but worth a mention i suppose, and also it doesnt work with powersaves for most games.....iirc it will only work with card2 games.....again probably not a issue for 99% of people, but on the other hand it was a disappointment to some users, but all in all it does what its intended to do, build quality seems to be fine, maybe the odd few doa cards, or poorly soldered buttons, but probably on par with doa gateway cards (or all mass produced flashcard in general)........if you feel you want one i see no reason why you shouldn't get one
