I bought 3 of these. Two never worked. The supplier sent me 3 more, but which time the third one had also stopped working. Of the 3 new ones only 2 worked when received. How long they will continue working I can only guess.
Bought this to plug a 16gb micro sdhc card into my Panasonic CQ-RX300N car radio which I bought a couple of years ago from the shop which takes its name from a Greek city in the Peloponnese. Having employed an HDD in a USB enclosure for some time I thought I would "upgrade" to solid state and I am happy to report that this has been successful. The card reader is tiny and is hard to see when plugged in. Recommended!
Update: it failed to work after less than a month, but it cost very little so I'm not about to lose any sleep.
Excellent Size, very portable, much better than normal USB sticks, however it is a bit on the cheep side construction wise and will not handle a lot of plugging in and out of micro SD cards , but is perfect for using a a permanent solid state Drive
