Just perfect fit on my Osmo pocket 2. I used to chip Samsung 128G SD card but this one had to go on my dashcam camera so this time I decided to get 256G. A little nervous on what if it wouldn’t work or recognize but nothing defective and works great so far. Let’s see how many times it can be rewritten, I’m very happy with my purchase. Reasonable price and fast delivery!

Reviewed in Canada on June 16, 2024
Size: 256GBStyle: Memory Card OnlyVerified Purchase
This card is FAST! Which is important for any kind of video camera where you don't want jitter or dropped frames.

I bought this for a body camera that I bought and it's been in there ever since.
I've had to pull off several videos from it and while checking the videos, they are stable, no glitching, no dropped frames, no audio issues at all. This is due to the high quality and high speed, both read and write, of this card.

I highly recommend this SD card.

Size: 512GBStyle: Memory Card OnlyVerified Purchase
In my past experience SanDisk has been very reliable. I use it on my 2k resolution security cameras and it's definitely fast enough. Since I've bought a few on these in the past and have a couple of adaptors already the missing adaptor wasn't an issue. Would have given it 5 stars if wasn't missing the adaptor.

5.0 out of 5 stars The Real Deal
Reviewed in Canada on April 27, 2024
Size: 256GBStyle: Memory Card OnlyVerified Purchase
I use this card to record 2.7K and 4k high bitrate video with my GoPro. It works and it holds at LEAST 85 GB reliably leading me to believe that this is indeed a legitimate product. I was admittedly hesitant to buy a high-cap SD card from Amazon given the plethora of Youtube videos showcasing illegitimate cards. I have always had good luck with this line of SanDisk cards amd I actually use a 64GB version in my DSLR for 1080p footage and High resolution pictures reliably.

This is the best card for your money if you can only have one card to hold EVERYTHING. SanDisk cards are my go-to and have held up compared to the other brand (starts with a K) whose cards have repeatedly died on me. The quality and reliability are just simply better.
