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. ### ⭐⭐⭐⭐⭐ Worked Very Well *by on Reviewed in the United States April 8, 2023* 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. ### ⭐⭐⭐⭐⭐ Great service and condition of product *by on Reviewed in the United States August 30, 2023* Absolutely just fine... Transcend 128gb micro SD card works for the T-Mobile Revvl 6 5G, so I'm pretty sure it works for the Revvl 6 PRO ## Frequently Bought Together - Transcend 512GB 300S, Memory Card, microSD, U3, A1, Up to 100 MB/s, for Mobile Devices, with Adapter - TS512GUSD300S-A - Memory Card Reader, BENFEI 4in1 USB 3.0 and USB-C to SD Micro SD MS CF Card Reader Adapter, 4 Cards Simultaneously Read and Write, Compatible with iPhone 15 Series, MacBook Pro/Air 2023, and More - PSP Memory Stick Adapter, Funturbo Micro SD to Memory Stick PRO Duo MagicGate Card for Sony PlayStation Portable, Camera, Handycam --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/406557206-transcend-512gb-usd300s-microsd-card-100mb-s-4k-u3-v30](https://www.desertcart.co.za/products/406557206-transcend-512gb-usd300s-microsd-card-100mb-s-4k-u3-v30) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-25*
