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.
These cards have been very stable and easy to modify. I modded my Nintendo DSi and 3DS with these and have tons of games on them. Of the 4 DS that I have, the ones with these cards have never had any issues, and it's been 2 months since install. Good luck! (I Don't use these for cameras or recording devices, but I would if I needed the cards, as these are also what I use in my GoPro)
