Micrso SD Card Adaptors - Basic vs Branded I cracked open a bargain AmazonBasics microSD→SD adapter and a branded SanDisk to see if the cheap stuff is actually worse inside. No speed tests—just a microscope look at the mechanics. The contact designs are surprisingly different: AmazonBasics uses thin spring fingers that seem prone to fatigue (the bit that failed on mine), while SanDisk’s contact block feels sturdier and maybe better plated. If you set-and-forget, both work; if you swap cards a lot, I’d pick the SanDisk. 28 January 2026
