To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The case is alright. None of the screw holes are pre-tapped, and the included screws are not the write sizes nor quantity. The case doesn't quite hold together correctly, and some of the buttons take effort to impress. The case also presses on the lower LCD display, causing it to flare up.
If you are going to use this case replacement, use the metal parts (screws etc) from the old DS and buy a high-quality screw driver. Maybe keep a file on hand to get rid of the sharp edges.
