## Description

Want to save space on your mobile device by running apps from a memory card? Transcend's microSDXC/SDHC 300S cards are the right choice! Compliant with the latest speed class, the cards boast excellent random read/write speed, perfect for retrieving small pieces of data from random locations and speeding app launch time.

Review: Great Choice - I love the price and the large storage space. I have had this particular sd card for only a few months, so longevity I can't say, though the reason I bought this brand was because I bought the 60gb, 5 years ago and its gone from my Note3 to my Note8 and still works perfectly in my note 8. I've upgraded to the note 20 and wanted a fresh card.
Review: Worked Very Well - Worked great copying my favorite music to it to play on my portable bluetooth speaker. I don't like using bluetooth much, so having a good portable speaker with TF/MicroSD card capable is great for me. This Transcend 32GB microSD Memory Card is great and I would recommend it to my family members and friends.
