I have a Mavic Pro and was having an issue with some videos not coming out right. Either unreadable or missing frames, etc. I discovered that the micro SD card I had was cheap and slow. This card solved the problem immediately. It writes fast, so my videos come out crystal clear. I had a concern about 128GB, being that the Mavic specs say 64GB max, but it works perfect.

I bought two of these from e-bay. The first was an exceptionally low price but contained in the small print that the card might need formatting to realise its full capacity. It showed correct capacity and files saved. But next time I opened card, half files were not there. tried several times and failed. Quick format did not resolve. Full format would not complete. I bought a second card at moderate price (half what you would pay in shops) but which did not have warnings in small print. This card has full capacity, saves and retains files and works perfectly. So I recommend this high capacity card, but check small print, as you need a card correctly formatted to full capacity or you may loose your files or photos above a cheaper cards (lower) capacity.

This card holds up well. I use it with my Sony Hx99. Shooting 4K videos is a dream. The smoothness of the pictures and videos shows well on this card. Upload and download speeds are amazing. I really can’t complain except on the price but it is what it is...
