I purchased for my Spark but never used what Mr Amazon called  "SanDisk Ultra 32GB microSDHC Memory Card + SD Adapter with A1 App Performance up to 98MB/s, Class 10, U1"

Suitable for my Mavic Air ?

Thanks

It's suitable if you're not going to shoot 4K video.  Otherwise, a UHS Speed Class 3 (U3) memory card would be best.

Hello and good day coxr1. Thank you for raising this inquiry. The supportedSD card for the DJI Mavic Air is a microSD Class 10 or UHS-1 rating required. I will be posting the list of supported SD cards for your DJI Mavic Air. Thank you.

Hi DJI Stephen, what about a Sandisk Extreme Pro V30 A2?
I have a 128GB Sandisk Extreme Pro V30 A2 and it started giving me pixalated videos. It ruined my last overseas vacation footage. It's like an old record being scratched. I tried a low level format, I did one more flying test and it's improved but I cannot trust the card anymore.
So I am looking to buy a new one, it's hard to find the A1 version. What is your recommendation?
I film only 1080P. Is this a good one?
