Pros
Kootion 64gb micro sd card ultra micro sdxc memory card u3 uhs-i tf card a1, u3, v30, 64 gb (2 pack) it has a total of 119. Gb of free storage capacity being close to the manufacturer specification. Formatting always uses some of the stated capacity. ... Read More
Twin microsd cards even come with an sd adapter for use with more common card readers. One goes in the side of a chromebook, the other in an android tablet. The usb card reader gets pretty warm but no different than most.
Gb is plenty of storage for video (security footage) they handle 4k recording with no issues. And once in a while, my handheld camera also have a memory not found issue, that i have to remove this memory and plug it back it for it to recognize it.
Kootion 128gb microsd card + usb 3. Is great. With the improvements in ssd and the speeds in m. Ssd these are good. The package includes a microsd card and a card reader.
Cons
Diagnostics results maxed at 4mb/s. It just says high speed. What the crystaldiskmark shows is 75. It is even less then other fake 128gig cards, formatting to only 116gig.
One of the micro-sd cards comes as defective. The product works, but writes slowly. These micro sd cards are not compatible and are difficult to get into the tablets.
I have no how this product is available on amazon or who is giving it such glowing reviews. Dead on arrival. Didnt work. Don't waste your money.
Highlights
Quality
Good price, good quality and just the perfect fit for my surface go 2.
For the price, the fact that you get 2x cards with 64gb is impressive!
You can get sandisk or samsung for about 10% more than this product.
Therefore we could never find the product.
Competitiveness
It is a nice product for its price, much cheaper than its competitors with the same quality.
I don't wish to wait a year to post a review, so for now it's 5-stars for matching their claims, at a decent price point ($19 / 2).
The card itself is rated to at least 30mb (megabyte) per second.
The sd card pair appear competitively priced and bit below the average.

The additional question is their longevity
Posted by a reviewer on Amazon
Im not familiar with this brand and im not sure if id trust it with missioncritical storage flying a drone for work for example especially if it requires high speed data to read and write but for something like a media player or dashcamsecurity camera recording this would be a great option to throw in

Well they would have to have their full stated capacity and not be fakes like some on amazon
Posted by a reviewer on Amazon
They would also have to perform at a v30 level while thats not a particularly high bar some still fail to clear it
Posted by a reviewer on Amazon
The measured performance is well above the v30 standard and almost reaches v60 territory
