Got to use in my new Moto G6 phone and works great. Have also used the 32Gb version for a previous cell phone and a 16 Gb and 2 32Gb Transcend SD full size cards for my Nikon camera for over 5 years. Never had any problem with any of them. Would highly recommend this brand for reliability.

A great card with consistent write speeds of 13MB/s on a slow tablet. Class 10 cards are rated at 10MB/s. This may not seem fast, but it is more than enough for media storage on my Tablet. Advertised as 128GB but once formatted it is 117GB. Read speeds of 23MB/s and consistent write speeds make this a great card. Highly recommended. If you are buying this for your phone or tablet make sure it supports 128GB cards as some only work with 32GB cards or smaller.

I've been using this brand for 10 years. I film with 30 to 40 action cams (Full HD) simultaneously for up to 12 hours per day in high temperatures. The cards handle 4K Drone footage equally well. No problem at all, as long as each card is formatted by the camera using it. Superbly reliable. Regards, Mike Cyber Editing

This micro SD card is exceptional value, with good speeds writing and reading. It has 117.7gb available in a Samsung S7. The supplier Sincerity trading is super fast and always sells original genuine equipment only
Tried so many off brands and over priced name brands and I keep coming back to Transcend SD cards. I've come to expect no fuss, no surprises or device conflicts from them.
I ordered these to use in my dash cam. The 256gb card gives my 24 hours recording time. Order arrived promptly without any damage and is currently operating with no concerns.
I have tried ordinary cards in my bleskysea b1w dash cam, Samsung evo had problems after 15 days, transcend card just stopped after 4 months without warning. This card works flawlessly so far. Works for me at ambient temperatures ranging from 20 C to 35 C.
Gee whiz it's so TINY but works so GREAT! Thank you! An excellent purchase for a very low price. Works like magic. No problems at all!
Wiko 5 now much more room for my photo backups. My MicroSD card reader was also able to read it OK>
it did not work properly . than formatting it was possible only with fat. after that i am still fearing that some files are transferred with incomplete content. not the best quality.
