Very good value for a 256GB SD Card

works as expected and extended storage in my Microsoft Surface Pro 3.

great

works with samsung phones! also with computers as extra memory and portable memory. It comes with the computer converter all you need is a card reader for those computers that dont have sd card slots but do have flash drive usb ports.

Works well for my security camera

Basically does exactly what I need it to do. Priced well, comes in a two pack and performs well in my reolink surveillance cameras.

Works as advertised

I really do not like Micro SD cards". They are just too darn small and extremely easy to loose. That being said nearly every new deice I get seems to need one of some nominal size to be fully functional. I put this pair into a new Alcatel Flip Phone and an Evoo 8 inch Android Tablet. They work as advertised and I can move on.

I give it a 5 for appearance

I give it a 3 on performance because i am at like 16 gigs and its telling me i am dangerously low on space constantly no matter how many times I archive stuff, cleaning the cache and emptying the trash, i keep getting this message. Other than that, I really like the chip. Its secure, i just wish i can use more of the storage on the chip.

Good Deal

My cheap phone can't take a storage card any bigger than 32G and I got two! I'm using the other one in my laptop for randomly backing up some files. I only wish I could interchange the cards instead of having to dedicate one specifically (and soley) to my phone, but that's a problem arising from the technology of the phone, not this card. It was/is a great value and I would definitely buy it again.

Just what I ordered

Works great for atorage in my tablet

GREAT product

I have just started to use one of these Micro SD cards, but so far, I'm extremely happy with it, and I look forward to continuing to use it. I purchased the SD cards to be able to use in my Android cell phone to increase the memory because I use my cell phone as my MP3 player, so needed more space to be able to store music. Plus, I also wanted more space for storing pics, files etc. I would highly recommend this product to anyone who uses their cell phone or anything else that takes a Micro SD card, and am very happy I purchased these.

Works great. I tested it with 2 software.

This review is for the 256GB sd card. This card was about $10 cheaper than other cards of this size, and I've been burned before, so I decided to test it. Attached are screenshots of my tests using 2 different software (fakeFlashTest, and h2testw_1.4). I only did the quick test in fakeFlashTest, but I did the long test using h2testw_1.4. This card passed both, so i am happy with my purchase. The speeds show 10.4MB/s write and 15.5MB/s read.
