I bought two microSD cards from two different manufacturers. Trademarks Kingston and other lesser known brands. Kingston went into my husband's three minute LG 800G prepaid phone (Tracfone) and was immediately recognized as external storage (3.4GB not 4GB but that was to be expected as there is always some wasted space due to the OS access system) . The included adapter also worked well, allowing me to upload music to the card from my Windows PC. In contrast, another brand (Patriot LX PRO Series Class 10 40MB/s UHS-1 32GB MicroSD card with higher speed and larger size) had problems. from the 90s to today. This product, like other Kingston SD and Flash drives I currently own, is of excellent quality and as described. Feel free to buy it if you need a microSD card that works properly, from the box.
