## Questions & Answers

**Q: Hate to even ask this, but is everyone absolutely sure that there are no fake cards in this pipeline of delivery ?**
A: I am not sure 100% I have purchased many cards. It wasn't till recently did I start to have quality issues with a certain card I purchased.

**Q: It says it is temperature proof, will it work in negative degree weather?**
A: Assume you mean in a "trail camera" type application, it should at reasonable "negative degree weather" as long as it is dry (water-tight).

**Q: Does this work with nikon D3300?**
A: Yes, it works great in the D3300.  Note however that it is the full-sized one, not a micro-card with an adaptor.  When I got it I thought I could put it in my tab and copy the pics but I needed a card reader.  Great card though, and works perfect with my Nikon D3300.

**Q: Can i use this in a macbook pro?**
A: Yes you can. I bought the Hyper Drive Hub that has 7 different ports. It plugs into the USB-C port on your MacBook. I have my wireless mouse USB plugged into it and it has a slot for SD cards. I’ve been uploading pics and videos to my MacBook Pro lien that for months. I hope this helps!
