I've had a success rate of about 50% with 8 or 9 of these adapters I've bought. Most failed adapters typically last 2 to 6 weeks, after which you'll see a "device not recognized" error message. I suspect it's a thermal-related issue, as the devices that are still running feel noticeably colder when I unplug them from the USB port. Those that fail are usually hotter to begin with and tend to get hotter a few weeks before failure. Despite this high failure rate, the cameras' memory cards were not damaged, and only in one case did an adapter failure result in the loss of the image data stored on the card. Until now, the price of an adapter was typically less than two dollars, making 4 surviving "hits" worth just ignoring the 4 or 5 "misses" that failed.
