But very tight to sert the card and pull out the card. Generally speaking, it a good one.

Love it. Wish I had purchased sooner!

I'm so glad I got this item because my old fashioned laptop computer does not have an SD card slot where you can slide it in by itself (without the SD card reader).

Product as described

I bought it because it was presented alongside of the cards I bought as being necessary for use with the cards I bought but so far among the cards I bought and the ones I already had, I haven't been able to get one to fit inside of it, either SD HC or SD XC so I don't know what kind of card fits in it but I know I don't have any of 'em.

I use this for transferring Pics and movies from older/smaller capacity cards to larger/newer cards. Works great, with good transfer speed.

I'm attaching screen shots of tests on the Sandisk 170MB/S card. One of them is using this SanDisk reader (175MB/S on read and 100MB/S on write), the other is using a generic USB3.0 reader (70-80MB/S overall). The difference is quite significant. This reader does pair well with the Sandisk 170MB/S card. My reader does not have the issue on the very tight card slot reported by other reviewers. The card slot works fine as a normal reader does.

If you have large SD Sandisk Extreme cards for your DSLR cameras....just get this card reader. I was blown away how fast it can copy LARGE files to my PC for editing. I was using the SD card reader in my laptop to xfer files from my 128GB xtreme card...and this one is night and day difference with USB3! I am totally pleased with it. for now 5 stars! Ill follow up in a few months to see how its holding up. Small, compact, perfect travel with in my camera bag.
