## Customer Reviews

### ⭐⭐⭐⭐⭐ Best bang for the buck with large micro SD cards!
*by J***E on August 2, 2020*

I have tested half-a-dozen different SEKC branded micro SD cards in devices ranging from portable handhelds all the way to cameras and video game consoles and not only is the card extremely fast to read and write to but it's cheap and just as sturdy as any Samsung or SanDisk card on the market. Luckily it's not an off-brand either because these cards are very well touted in Taiwan and if you're lucky you'll even see a few with SanDisk controllers internally. These cards come in at almost half the price of your high end Samsung SD cards but they're every bit as reliable and fast, so my last order was for 4 of the same 512GB micro SD cards I've been using for 4 months now. I hope the brand becomes more popular (or kept a secret so that the prices stay as low as they currently are ;-). I believe that this brand is right in line with the likes of both SanDisk and Samsung.

### ⭐⭐⭐⭐⭐ 3 out of 4 work great!
*by D***Y on August 14, 2020*

Purchased 4 of these as I've expanded my security system and have 1 that seems to have failed.. It just quit working. Can't reformat it, it's just like it doesn't have a card in it. Ordered a replacement as the 1 month Amazon return policy has expired by a couple weeks.

### ⭐⭐⭐⭐⭐ Storage keeping up with Gordon Moore's prognostication.
*by O***R on January 22, 2022*

120 Gb with U3 I/O speed. That was a great deal in 2020, but last year one could do better.My mistake was in not checking prices. Now you can get 256 Gb, twice the storage, for only $5 more.Make sure you're getting the fastest RAM available -- it's called U3, which is easiest to remember. Look for the highest random Read and Write speeds. The 256Gb card was the best price/performance deal last year. 128Gb is still plenty of memory, but take a look for 256Kb or even 512Kb U3. They might be a smarter deal the next time around.
