What is broken?
Still if you open those up the warranty is gone. IF they are still under warranty i would just send them to Nintendo to get them fixed AND keep my warranty.
That's what I'm saying, all broken, sending in for warranty

They each have a sort of different issue. One won't charge, one won't stay powered up (turns on, then shuts off 2 seconds later), and the 3rd works for about 1-2 minutes before giving me an error message telling me to turn the unit off. All are basically brand new, including the boxes (obviously), all paperwork, chargers, cradles, etc. One was registered when it originally sold, which meant just filling out the online warranty claim info, and the other two weren't registered by the original retailer. A quick phone call and they're on their way as well (ALL red 3DS systems are still under warranty, which is a big part of why I risked buying this auction).
