Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Paired this with a Canon 90D, perform well, I don't seem to have any memory card limitation problems. It arrived quickly. I don't think there is much more to say about this. It does the job, not recorded much video though, but what I have recorded again seem fast.
I bought 4 pieces of this item to be used on my new Sony A7 III - but at the end of the day, the cards don't work as expected. They always stop in the middle of video recording. It's quite annoying and embarassing.
