Went to buy a micro sd card for my new SJ4000 action cam and the sales guy keep pushing me to buy the more expensive type (SanDisk Extreme Plus) which he says is more suitable for action camera, but cost almost double than normal micro sd card. Wondering can I just use the normal Class 10 (80MB/s) micro sd card since I'm probably just going to use it once or twice a year when I go snorkeling during beach holidays?
Sales guy told me the normal type is useless with action camera and easily spoiled.

That's good to know. Thanks!
