Everything I needed and more
Color: White
I honestly think this may the first time I ever reviewed a product but I felt like I had to because this thing absolutely ROCKS. So easy to use, so fast, and affordable!!! Finally getting back into photography again thanks to this little thing. I wasn't sure if it was going to work to be completely honest, but it works and it works great! You can connect it straight to your iPhone, plug in the SD card, go into your files app, and all your pics from the SD card will be there ready for you to choose which you want to download to your photos. Truly everything I needed and more!!!!

It really works… just one gotcha to be aware of…
Color: White
This little thing is the bomb! I compete in several dog sports with my two dogs, Punk and Shout! I video all our runs with a 4K action camera (GoPro knock-off). The app doesn’t work with my camera, so the only way to scroll through the videos to delete files I don’t need is on the camera itself. It’s very time consuming to watch each video (1-5 minutes long) to see if I need to keep it or delete it. And there is no way for me to process the videos on my phone to post them to FB while at the competitions. So when I found this gadget, I was super stoked. We had a very big 3 day agility competition last weekend, and I was able to use this for the first time. I could easily identify the videos I wanted, download them to my phone, make movies with iMovie, and post them to FB to brag on my dogs. SO VERY HAPPY with the ease of use and reliability. It worked each time I connected it to my phone, it read the micro SD card consistently, it downloaded the videos as selected. I will warn you — do not use the files app your phone to delete videos from your card. Use the camera to do that. I tested it beforehand and only verified that the videos didn’t show up when I put the card back into the camera, assuming that the videos were actually deleted. Unfortunately, when I did this over the weekend, even though the videos seemed to be deleted, the file space on the SD card was not released. So, my 128G SD card filled up even though I only had 30 1G videos visible on the card. I missed filming one very important event because the camera shut off because the card was “full”. I had to use a different SD card (lower quality) for the rest of the trial. When I got home, the only videos I could recover from the card were the 30 videos, yet the card was still full, even after deleting those 40 files using my PC, the properties of the card still show it full of phantom videos. The only way I could recover all storage space was to re-format the card. So… just beware when deleting files using the Files app on your phone, it does not free up the space on the card EVER. As a backup plan, I ordered 2 more high-speed Micro SD cards, so I should not run out of space for another 3 day weekend. Overall, I love this little gizmo and will continue to use it A LOT!

Very good
Color: White, Color: White
I have an iPhone 8 and it worked well with this. It was very simple to use. I was able to get all my pictures from my trip and the card fit in nicely as well. I would recommend this and I think the price is right. I was able to get the images right away, it was very fast.
