SanDisk High Endurance MicroSD Memory Card

[Warin]

Regular. But a good brand.
Given the price drops and increasing capacity.

Usually when I first purchase the device .. the cost are such that I buy cards at about half the max capacity of the device (most memory for the $).

After a year or two or five the prices drop and the max capacity goes up. About this time I buy the cards at the max capacity of my device (now probably the best bang for $).

Another few years and the prices drop and the max capacity goes up again. The max capacity of my device is now at the minimum size card that you can buy . I'll usually buy a few more cards .. depending on my expectation of the devices life.

--------------------
Some cards have a warranty .. my latest ones are 10 years. In 5 years I'll probably be buying the smallest capacity cards at the same capacity as these ones. So .. in 15 years time I will have run out of warranty.
