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.
My brothers D3100 didn't come with a cable! Can you imagine that. He was constantly removing the SD card to retrieve his photos and I knew it would be just a matter of time before he broke the access door or forgot to remove the SD card and go on a shot with no memory card. I bought this for him and it is much easier to connect. Works great. No problems.
