KOOTION 128GB Micro SDXC UHS-I U3 V30 A1 Memory Card - High Speed TF Card for Phone, Camera

I bought one of these at Walmart and it was trash. So I bought one from Amazon and it was good. What more can I say? I've had it for 2 years in my phone, without any data loss.

Purchased to use with indoor cameras. They were compatible, and have been very reliable for us. We are happy with the quality and ease of use for these SD cards, and they were a great price! Highly recommend!

I've been using these in my wireless security cameras for about a year now. The camera's constantly record and I've not experienced no data loss or any other issues with these SD cards. I Have 5 in use.

I like the memory card , but the actual Physical card itself was far to big for the Slot it was supposed to fit into on my Video cam and so that was a draw back !! Obviously the person didn’t know what was the right size micro Sd Card for the device they were pairing it with ( it wasn’t A Brand Name Match ) ! I’m sure it will work with something !?

Excellent

Buena oferta, buen producto, estoy satisfecho

Well, of course I was super excited to receive this and up the storage on my phone (for a low cost too). I was nervous about moving my files so I waited longer than I should have to pull the trigger. Finally, when my other SD card just couldn't save any more, I knew I had to make the switch. I successfully moved everything over to the card and inserted into my phone. I noticed initially that the items didn't move over immediately, so I checked all my settings; everything seemed good. Tinkered around with my phone and kind of just gave up. A bit later, I saw that the files (photos, videos, etc.) had successfully transferred in to the phone so I assumed it had just needed a little time since it was a large amount of data. Well, fast forward 2 weeks and I am simply looking at FB like I sometimes do. I realized I needed a photo for my business, so I went to my gallery. To my shock, the majority of my photos and videos were gone. All the photos I know I had saved to the SD card were just gone. I had not changed any setting, formatted the card, and I am 100% positive they were there the previous day/night. I decided to go to my phone carrier to see if, by some chance, I had done something in error. NOPE!!!! Associate showed me that the card was not registering on any device; not just my phone! So save your money, and use it towards the name brand options for only a few dollars more. Luckily I saved all my stuff to a hard drive before I copied it to the SD card, but I still lost everything I had saved in those 2 weeks of the card somehow working with my phone! So pissed!!! I am out my SDcard/money AND my data!

The KOOTION Micro SDXC memory card is fantastic! It has plenty of storage space and works flawlessly with my phone and tablet. I’ve transferred large files and videos with no issues, and it’s super fast. The card is reliable and holds up well under constant use. I also appreciate that it comes at a great price without compromising on quality. If you need extra storage for your devices, this is an excellent choice.
