By cons WARNING! Indeed, to read micro SD cards you will need a Adapter (which has the form of an SD card in which you insert your micro SD card) in order to read its content and perform operations (copy paste, etc. )
Otherwise no downside at the functional level, you can read the contents of the card but also move files, delete, etc.
Design is not a criterion in my eyes saw the usefulness of this product (help those who do not have a SD port on their PC) and in any case it is correct.
In summary, a nice product that delivers an unbeatable price, but for which you need to buy separately an adapter (which does not cost much!) To read the contents of micro SD cards
