works good no issues or design flaws perfect for memory card adapter if you have an older digital camera you may need this as well to transfer to iphone

Works as it should

Reads every card I've put into it so far

As others have stated, SD cards are a really tight fit. It also didn’t seem to work with a couple of very very old SD cards, but that could have been an issue with the cards themselves. Worked fine with several memory stick devices as well. Build quality could be better, but can’t beat the price. Speed was fine for a usb 2 reader. One thing I found that greatly helped with smooth operation was to unplug the device before inserting or removing cards.

Muy bueno y funcional

The memory stick slot did not accommodate the thick original memory sticks. MS Duo worked for 2 days and then stopped working. Other slots worked OK

Got what I paid for.

Didn’t work, waste of money
