    AWESOME for 4k recording

    Reviewed by Al - January 5, 2020

    These 128GB microSDXC class memory cards are AWESOME to use with your QUADs Drones when recording @4k. You need the speed of the 633x memory cards to save your recordings fast and quickly.

    Good Quality SD Card

    Reviewed by Shawn - March 13, 2017

    I haven't really stress tested the I/O speed on this card as I bought it to increase the memory on my phone. But it seemed quick enough when copying over files from the laptop. Bought it on sale and price was right. It's worked everywhere I tried it and it's been reliable so far (only been using it for a couple of weeks though).

    Fine

    Reviewed by Holly - August 28, 2019

    Got it a week ago, works as it should. I can play video right from the card no problems. I think it's cheap because of the write and read speed.

    Corrupted

    Reviewed by Seth - January 29, 2023

    I got "corrupt data" error messages on my Switch every time I tried to use it and I couldn't download anything, so I did a write test on my computer and it turns out that it's pretty much useless

    No, I would not recommend this to a friend.

    great product

    Reviewed by Matt - October 13, 2019

    using this microsd on my Gopro hero session and have zero problems with it. I used to use my sandisk extreme microsd,but needed more space (It's only a 32gb). This one is lightning fast on the Gopro and on the data transfering. Not THE FASTEST,but perfect for the price and will not let you down.

    Helpful service

    Reviewed by CTC - November 29, 2025

    Staff helping me was very knowledgeable , courteous and informed. I needed a micro SD card for a digital frame and was made aware of the number of photos each card could hold. This helped me purchase an appropriate sized card, saving money on a two pack for gifts.

    Yes, I would recommend this to a friend.
