KOOTION 64GB Micro SD Cards 3 Pack Memory Card U3 SDXC High Speed TF Card 4K Full HD Video for Phone, Camera, Security Cam, Tablet

The cards are small but fit perfectly in my surveillance cameras. Great price. Even comes with an adaptor so I can view the pictures on my computer.

That they work as well as other brands.

I was a little skeptic purchasing these microSD cards from a brand. I haven't heard much about. However, the value was so great. I couldn't pass it up for this five pack of 64 GB microSD cards from Kootion I figured I'd just give it a try and see how it goes. First of all the speed was amazing. I didn't notice any leg compared to the more popular brand SD cards that I have they work great in my security camera system as backups from the cloud storage. I trust these SD cards enough to use them without a cloud storage. So I'm probably gonna end up canceling that and just stick with these cards. Overall, I ended up buying another five pack just to have some extra and have added this brand to my trusted brands of flash storage. Very satisfied and won't hesitate in buying again.

after I moved movies to my card, they were crystal clear, I rated these cards a 4, because of speed transferring, I would have rated 4.9, I will be ordering more of these cards, very very good, the quality is outstanding,

These memory cards work great in my security cameras. They are much quicker than my old Sandisk cards. Good price.

Great value for this GB-sized sim card that will be used in multiple CCTV cameras in my apt.; perfect for intended use. Shipped fast.

I don't know how they function or anything because I never received the camera

I got these to use in a digital camera to have more photo space. They did not work and were not compatible at all. The error I got kept saying SD card Error. I tried all of them too. Thankfully I had one that did work. The labeling does say that it works with the cameras but does not say if it specific ones.

I had this heater for one month.And while I was sleeping smokestart coming out of the back of it , it shorted out

I ordered the three pack of SD cards and the adapter and only got two SD cards and the adapter but other than that I'm happy with the product
