## 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

God r/w speeds, SD card adaptor is wonky and gets stuck on read-only mode sometimes. Unsure about longevity, however.
