Bought both this and a similar Transcend Premium 300X 32 GB MicroSDHC Class 10 UHS for a couple of G1WH dash cams.  Both work well with the cameras.  The key is you need cards compliant with UHS 1 or better.  Look for the U with a 1 or a 3 inside it on the card for these cameras.  The Transcend is rated slightly faster but the cameras seem to like either equally well.  When I purchased this Transcend and the SanDisk were within pennies of each other, so aside from slight price and speed differences, there's not much to recommend one over the other.  And so long as you get at least a UHS 1 card, the same can be said for other manufacturers such as G.Skill, Kingston, or others.
