Review: Compact, Sturdy, and Functional - This will be generally first impressions because I've only been using this for a day, but I wanted to also touch on a few concerns I read in other reviews. First off, the design is actually pretty simple but nice. I would guess an aluminum casing with the Kingston branding accompanied by a black plastic back for SD and micro SD insertion with a honeycomb pattern. It looks sleek and its not bulky or heavy at all. I don't really know how to do a speed test. The device using USB 3.0 but I'm gonna assume that the speeds will still vary greatly on the SD card used. I used a Sony SDHC 70mb/s class 10 32GB card to run basic tests. The speed wasn't bad but if you expected USB 3.0 speeds, it will underwhelm you. I think with the USB 3.0 you'll get roughly the max speed possible with the card so I do like that the device is USB 3.0 compatible but experiences will vary. Touching on the two main concerns I read about in other reviews. Heat and size of the port. I left the drive plugged in with reading or writing to it for over an hour without any major heat issues. It did get warm but, nothing out of the ordinary or dangerous. I also tried reading and writing large files to it and while I experienced slightly more heat, it still did not seem hot or dangerous. Also, I read that the port was a bit too snug for USB ports making it hard to insert or remove and even cause the back casing to come off in the process. I did not experience this either. I tried both of my USB 3.0 ports at home on my computer and I tried two separate desertcartBasic USB extenders(1x 2.0 / 1x 3.0) and found no extra difficulty inserting the drive or removing it. This could be a batch issue but as far as my device in 12/15, I didn't have this issue. Overall I like it. I don't like having to carry cords around for all my devices to plug into my computer and transfer files. I can carry this around or leave it plugged in as a SD or micro SD reader which my computer does not have. For now it has been functional and for the price of ~$9 I can easily recommend this. If it doesn't hold up to the test of time, I will come back to change my review.
Review: Hands down.. Best portable USB 3.0 card reader yet - Needed a card reader that was portable, but could also allow UHS II speeds to work. This reader has gone beyond my expectations, enough so that i wanted to tell others. It is SOLID... made of metal and not plastic. Unlike others who drop out occasionally, this has not. It achieves the correct speeds, including UHS II cards like Lexar's lineup of super fast sd cards. But the icing on the cake is that it allows both cards (micro and full size SD/TF) to be recognized by the OS CONCURRENTLY. I always thought that was a crappy feature of other brands... Make two slots but only read one at a time. The metal construction is the best ive owned thurs far though... And i plan to purchase a few more to have on hand at the shop, home and possibly on a keychain. Only thing i did not expect is that there's no end cap.. But most get lost quickly anyway. So 5 stars, all the way. I would definitely recommend this item if you are looking for a solid usb 3.0 card reader, if you require UHSII reading, or if you just want a reader that is reliable. Great device, and the price is right under $10. Worth it IMO.

### ⭐⭐⭐⭐ Good card reader, but gets quite hot
*by G***G on September 19, 2015*

I've had this card reader for several months, and it works well. What really separates this card reader from others is that it's USB 3.0 and supports not only UHS-I, but UHS-II, while being quite cheap. My only complaint is that this card reader gets really, really hot while plugged in, even if it's not in use. I touched mine a couple times and quickly removed it. It doesn't seem damaged or anything, but it gets way hotter than I expected. At the time, I almost didn't end up buying it, because Amazon didn't have it listed under featured, new products, or anything that stood out. Amazon makes it hard to quality products at times, relying so much on reviews (older products usually) and other criteria which even well reviewed products may not fit into.
