1. The reader fits both SD and Micro SD cards. You can have two cards (one of each type) inserted at the same time (Pictures 1 and 2).
2. I use G4 with my old GSM Micro SD card (Picture 1)—as a backup thumb drive for watching movies and listening to music on an LCD TV. G4 is perfect for this purpose.
3. The interface is USB 3 (please, note the blue inside plastic, characteristic of the faster format in Picture 3). While the USB 2.0 standard offers a theoretical maximum signalling rate of 480 megabits per second, USB 3.0 defines a maximum rate of 5 gigabits per second. In other words, USB 3.0 is theoretically more than ten times faster than USB 2.0. Under real world circumstances, USB 3.0 drives deliver speeds between 70 and 115 MBps. Please, note that the actual speed of Kingston MobileLite G4 will depend on the quality (class) of the SD or Micro SD card that you use it with. This is not a “fast” or “slow” SD card reader—you need to buy a fast card (Class 10) if you want your card reader to perform well.
4. The housing is made of (mostly) metal.
1. As shown on Picture 4, this card reader is 4.8 cm long (6 cm with the SD card sticking out from the slot), 3.3 cm wide and 0.8 cm thick. Of these three, wideness is the greatest challenge, because when you insert G4 in a USB port, it will partially cover neighboring ports too—and render them unusable (Picture 5).
2. G4 gets very warm in the process of transferring files.
3. Customers have reported that the drive falls apart with the metal and plastic components detaching from one another. However, I have used mine for over two years now and I have not experienced any build problems. Still, this might be something to consider.
4. SD cards stick quite a bit from the backside of the reader and may get pulled out or damaged if you transport G4 with the cards in.
1. At 8 GBP, this card reader is a great bargain. Kingston is a well-known manufacturer of SD cards, solid state drives, thumb drives and accessories.
2. G4 is very convenient to use with the SD or Micro SD card of your preferred size and speed.
3. The reader gets very warm when transferring files.
4. It is 3.3 cm wide and will block your neighboring ports. For a laptop, this is a serious problem.
I found this from Kingston, took some of the reviews with a pinch of salt after reading them very carefully as you always get the 20% idiots who are clearly reviewing the wrong product or just need to go back to common sense school.
Anyway. If you need a USB 3 card reader for microSD or full size SDHC or SDXC cards, stop searching and just get this one. You won't be disappointed.
Fast postage, well packaged, plug 'n' play and top quality. Enjoy...
Testing involved two (2) SanDisk Extreme Pro cards; one 64GB, one 128GB, both UHS-I 95MB/s cards, and one (1) Sony SF-G128 128GB UHS-II 300MB/s read 299MB/s write.
All tests were conducted on CrystalDiskMark v5.1.0 x64 using a Delkin Devices UHS-I card reader, the Kingston MobileLite G4 reader, and a Samsung 860 Evo 1TB M.2 SSD in a USB 3.0 enclosure to ensure the USB port itself was fully functional.
Test bench specifications:
Intel Core i7 6950X
Asus X99 Strix Gaming
64GB (4x16GB) Kingston HyperX Fury Black 2400MHz
Mushkin Reactor 1TB SSD (Boot drive)
Phanteks Evolv ATX TG Front USB Port
TL;DR: Buy only if you have UHS-I cards.

Looks like I don't report the read times. So I'd say this "card reader" can drive a class 10 flat out (via USB3 on Linux) the card itself (not being reviewed here) seems to have some "go faster" bits which are good for the 1st 30% , which I suspct is more than most folks write at a time.
I bought the previous G3 version to read (and test) San Disk Extreme Pro but despite a very fast PC and cards rated at 95MB/s, I could only get 40MB/s from the 32 and 64GB cards and only 20MB/s from the 128GB cards. I though that the 128GB card was a fake, but it seemed to perform in the camera, so in hope more than expectation I bought the G4. Finally I get can speeds near the rated 95MB/s (84 read, 79 write) with this reader.
Given the 95 is "up to" I think the 10% loss is more than acceptable.
Because of the confusion -1, 4/5
