PSA that these, along with the recent Samsung cards, use a proprietary extension of UHS-I to exceed UHS-I speeds. You won't get the higher speeds without a compatible card reader. If you haven't purchased one of the bundles with compatible card readers, the cheapest one I've found is the Kingston UHS-II reader (not sure if the microSD version applies as I have not used it): https://www.amazon.com/Kingston-M...085P4Y1F1/

Any UHS-I card exceeding the UHS-I limit of 104 MB/s is using that extension. Accordingly, that will be the transfer rate limit if you do not use a compatible card reader (hence some of the angry reviews).
