These items represent great value for money. They're inexpensive and readily available, but there are caveats. The transfer rate is very slow, so make sure you have enough time for data transfer. What is worse, however, is that large files cannot be transferred. I tried at least 10 times to upload a 7GB video but couldn't upload an error code. I ended up having to compress the video to get the full length. Again, they're good for storing some things, but they take a long time to do so.
