I got a R4i Gold 3DS RTS about a 6 months ago and to be honest it's garbage at least mine is. It would always get stuck in the 3DS and I would have to push on it very hard and about 10 times to get it to eject. The 3DS sometimes wouldn't recognize it and when I managed to get into a game if I ever slightly nudged the 3DS the game would freeze. It was obviously a contact issue so I had to resort to putting stickers on the cart to add some thickness and it works slightly better but it's still garbage.
