📷 Gigastone 256GB Micro SD Card: Gaming Plus, Nintendo-Switch, 100MB/s, 4K Video, Action Camera, GoPro, Dash Cam Review

I use it on a DVR. I worked well for a few hours. Then the stroke was no longer a record. I took it out of the dash cam and tried to read it with my computer but the computer can't read it. I accidentally bought two micro SD cards. I've been working with the second one so far.

I've only used it with Switch so I can't comment on how it works on other devices. As for the Switch, this SD card works great. No questions. I've almost used up all the space on the card (only 8GB left), so that should tell you it's doing the job. I trust and recommend it (for use with Switch).

They correspond to the information in the manufacturer's specifications. So, no video for me on this trip. Waste of money on camera, accessories, batteries and memory cards as I can't use them.

Checking the card, adapter, restarting the computer, I even searched on google and downloaded several programs to unlock the locked SD card. Nothing worked. I couldn't return it because the return window was closed. I called Revane who

This thing is nonsense. I bought it to use in my Fire TV Box but decided Fire TV couldn't read it in less than a day so I replaced it with the card in my phone since it likes my phone looked could read it. Well, the joke was mine, because even though my phone recognizes it's there, it can't use it at all. Card and I told them about the issues I was having with it and I can say they did a fantastic job of trying to fix the situation. They sent me a new card which is still working great and also…

These 128GB microSD cards were said to be "Android compatible" and according to reviews they should work on a Kindle Fire 8 tablet. The second day after I put them in my Kindle and Android phone (LG Power X), it turned out that the Kindle was "incompatible" and "ejected unexpectedly" according to the tablet when I woke up. All of my apps that were moved to the SD card were unusable on my Kindle. I had to put the SD card back into the computer, format it and download it again to get it working…

I bought seven of these cards (128GB) which come with a 5 year warranty. Three of them failed within 10 weeks. I tried to contact Gigastone but found that the security certificate on their website had expired over a month ago. I still tried to fill out the online form, only the submit button didn't work. I tried it in two other browsers with the same effect. So I found the email address on the package and contacted the company. I received a response within a reasonable amount of time (perhaps…
