Everyday users generally appreciate the low price, sturdy metal build, and convenient OTG functionality, especially in multi-color packs for gifting or organization. Recurring complaints focus on the slow USB-2.0 speeds, unclear usable capacity, occasional boot failures, and doubts about review authenticity.
