When I bought these Revain had a 3 pack discount coupon so basically I have 3 of them get $2 each. I can either give away two or lose them strategically. I got them specifically for accessing micro SD cards, and they're almost perfect for that - note that with micro cards, the card just slides in, there's no skipping. This leaves just enough of the card for me to easily control the extraction time (removing the card is not difficult). They also don't duplicate a USB port, they just have slots for different types of SD cards. Finally, the case is just a bit bulky, so if you have two USB ports close together, it could hit the connector you put in the other port. I'm not complaining though - it's a convenient and inexpensive way to mount and access a micro SD card if I only have devices with USB ports. :)
