## Questions & Answers

**Q: Will this  work on a Dashcam?**
A: I would only use this for 1080p dashcams. Anything 1440p and higher, find a faster one. The "endurance" cards are useless if they can't support the write speed. I learned the hard way.

**Q: What company makes these? i get that it’s amazon, but is this samsung or another company?**
A: Longsys Electronics makes these cards.
They also make the chips used in the Lexar brand

**Q: do i use this for more kindle devise memory?**
A: Kindle accepts standard size SD cards, not Micro SD cards. However the adapter that comes with every Micro SD card, allows the Micro SD to be read inside devices that only use standard size SD cards... 
Since the adapter turns your Micro SD into a full size card you ​could use it with a kindle, but it needs to be INSIDE THE ADAPTER. 
The adapter allows interoperability between devices, so you can transfer bulk files easily from your kindle to something needing a micro SD, like a cell phone.  
It mustn't ever be inserted to a kindle as a microSD without an adapter, it'd get stuck in the slot, and you'd only have on board storage available. 
If you're at all unsure about how to use the adapter, or don't need to use it in other devices at all, full size SD cards (which don't need any adapter) are actually cheaper the their micro SD counterparts.  
Here's an example of a full size SD card, that you could insert in your kindle without an adapter (it costs a bit less too). I hope this info helped someone!

**Q: Can this be used for Galaxy tab A8?**
A: yes ... a microSD card fits

### ⭐⭐⭐⭐⭐ Miles of Memory in a Small Red Field
*by J***M on March 5, 2026*

I’ve come to admire small, dependable things—the sort that quietly do their work without fuss—and this Amazon Basics 128 GB microSD memory card is very much that kind of companion. It’s a modest little square of technology, but it holds an impressive amount of room for photos, videos, and files, like a field that stretches farther than you first expect when you step out onto it. Installation was simple and quick, and the included full-size adapter makes it easy to use across different devices. I’ve used it in a camera and a tablet, and in both cases it performed steadily, storing and retrieving files without hesitation. Transfers are smooth, and it’s reassuring to know that such a small card can keep so much safely tucked away. There’s something satisfying about reliability like this—no drama, no complication, just quiet usefulness. For everyday storage and dependable performance, this memory card walks a good road and keeps its promise the whole way. Five stars without question.
