Fake card

so it doesn't protrude so much from the laptop but the card itself is great.

With that in mind, I have never tried using the very cheapest card or too-goo-to-be-true card deals

I've used lesser quality cards and truly regret it now with non-replaceble videos lost on inferior cards.

I found more inexpensive cards from unknown companies, but for a few extra bucks I’ll go with SanDisk knowing the quality is going to live up to my expectations.

I decided to wait a while before I posted a review until I received my Portable Card Reader later this week to just make sure I was a problem with the adapted and not with the whole product

Reliable SD card

Brand name authentic SD cards

I don't know what happened, I normally have excellent experiences with SanDisk, all my sd cards are the same brand, but this one sucks (128 GB)

BTW, personally I've never had any luck using these cards for sandisk with 4k action cams.

You should always fill up the card with 90% of the stated capacity to verify that you have received a genuine working card.
