KOOTION Micro SD Card 64 GB 2 Pack Micro SDXC U3 Memory Card High Speed TF Card for Phone, Camera, Security Cam, Tablet

good price for the amount of SD cards in the package

I was a little skeptical, because I was reading some reviews on other items similar to this one. Glad I took a chance and purchase it. It was easy to insert, video clear. I use it for my camera. Definitely will purchase again

it was just what i needed

my wife, daughter and I are using the SD cards.

They arrived in a small envelope in the mail box, 5 microSD cards and one SD adapter, and so far they have been exactly what i needed, easily transferring data from the pc to the phone to the mp3 player and the tablet. i got exactly what was advertised, in new condition. The way online orders should all be.

At about half the cost per card of name brands they are cheap. But that comes with significant trade-offs. Write speed is 3.6 Mb/sec which means about 1 1/2 hours to write 32 GB. But the cards only format to 29 GB. I thought I didn't care about performance since I mostly wanted to backup other cards. But there wasn't space to hold all of another 32 GB card. So far, all of the cards "work" within the above performance. Bottom line I'm wasting hours of my time to save a few bucks.

They don't work on none of my devices.

I bought a pack of two and one was cracked and the other one works , but as time has passed it gets frozen some times and the pack of four does not work at all , i have tried everything but doesn't work , so i need to return .

The SD cards were delivered extremely fast. Unfortunately not all of the cards work, even after formatting. It was a great price but it would be nice if all cards could be used at least once. I tested the cards in the same slot so no variable except the card. I wonder how long the working ones will stay working.

I was looking for micro SDHC 32GB memory cards at a fair price. I thought I hit the jackpot when I found a pack of 5 from Kootion for about $20. The package arrived at my home sooner than expected. I put one in my Wyze Cam v2 home monitoring camera and noticed the Wyze app said it was only about 1.3GB. So I had the camera format the card. No change. Then I thought I would try formatting the card in my Gateway laptop (just purchased last Christmas). It had trouble recognizing the card. After reinserting the card several times, it did finally show up in Windows file folders (properties showed the correct card size of 32GB). I proceeded to format the card, which it could not complete. It said there were problems and suggested a scan to fix errors. So, I tried that and it failed. Then I went through the same process with a second memory card and got the same results. I did not waste my time on the other 3 cards. The 5 pack is being returned FedEx today. Sorry for the plugs on some other products I own :)
