[5-Yrs Free Data Recovery] GIGASTONE 64GB Micro SD Card 5-Pack, 4K Game Pro, MicroSDXC Memory Card for Nintendo-Switch 1, GoPro, Security Camera, DJI, UHD Video, up to 95/35MB/s, UHS-I U3 A2 V30 C10

Yes, I know, when it comes to memory, 512 is not actually 512, and that is the only negative thing I can say about the card. It's 470GB. Still, that is plenty enough for what I use it for, which is game downloads for the Nintendo Switch. There are no capability issues with the Switch, and I haven't noticed any delay or lag in it retrieving data from the card. Highly recommend!

So I got the 5 pack of 64Gb U3 (for $42). All 5 work, no problems. They seem to be just as good as the more well-known brands, but less expensive.

I have a lot of action cameras and drones. I try to make sure that I have plenty of cards for all of them. This means a lot of cards. I don't really need the biggest (most memory) cards available. I generally download the video or change cards after every flight (or every ride). But, having one card already loaded and formatted, then one spare available for each device, prevents me from digging around, looking for another card.This is not my first purchase of Gigastone cards. The devices that I use, and the video that I create, pretty much demands that I have good quality, 4K UHD UHS-I U3 cards. I also prefer the extreme 633X speed, for the smoothest video at the best clarity that my cameras can provide. Your memory card should NOT limit your abilities, when shooting high speed action from either your drone or your action camera.Gigastone has not let me down yet. I have never had any problems with their cards. And, I always enjoy a quality product, when viewing my videos. No matter how fast, how rapid the transitions, how demanding the environment. Finally, Gigastone's product is considerably less in cost than many other well known brands.These are great cards. I depend on them and am always pleased with the results.

This microSD card works fine and records 4K video without slowing down. Works great in my phone!

They seem to work great in our Heroes 8Black GoPro.

I love how easy it was to install in the switch and overall super nice definitely will get this again once I get a second switch

Product was well packaged.Memory cards work as expected... though appear to offer 58gig of storage on a 64gig SD memory card.

This micro SD card doesn't work with the insta360 x3 action camera. Do yourself a favor and go to the storage section of the insta360 website for compatible micro SD cards. This camera takes a specific format of micro SD card. Other than that I'm sure this is a great product.
