well,i have had mine for a few monthes now,and it had no problems whatsoever. just be careful with the dsi,because it feels very fragile(especially the matte finish ones,i liked the matte finishes on the dsl better xD). i reccomend,to keep it super safe and all,get a case,like one of those fancy aluminum ones. i have a transparent casing,but when i put it in/take it off,i'm always worried that i may scratch it. some screen protectors as good ideas too. always make sure that your hands are dry,because my friend played his so much,his hands got swaety and it messed up the buttons. srry if i talk too much....xD
