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 analyzes reviews to verify trustworthiness.
I have bought several of these to use in our Foscam R2C and R2 security cameras. They work great. And they were shipped fast to us is simple small packaging. Will buy again when I need more of these micro SD cards.
Update 8 Nov 2019, one of the cards has burned up. Indoor security camera stopped working and I found I had to remove this micro SD card to make the camera work. Put the card back in and the heat from it burned my finger. Then upon removing it I found it has a small black burned spot on it. Cannot find any way to contact the MFG for the warranty even though the Amazon page says 10 year warranty and past the Amazon 30 days. So I guess I will not be buying any more of these. I've never had any other card burn up like this. Downgrading the 5 star to a 3 star because only 4 of the 5 cards I purchased still work and it has only been 7 months.
