COCOCKA USB

An exellent SD/Micro SD card reader at a great price. The USB 3.0 and USB-C connectors make it an extremely versatile card reader with data transfer rates only limited by the read/write speed of the SD/Micro SD card itself, and it could not be easier to use. Just insert the SD/Micro SD card in the reader then plug the reader into your computer with either USB connector where it's instantly recognized, no set up required (the USB 3.0 connector will work with a standard USB 2.0 port but without the higher speed of USB 3.0). My initial transfer of approximately 45GB of data from my laptop to the Micro SD are from my phone was simple and completely error free. I did not rate it for durability as I've only had it for a couple of days. If any issues arise I'll update this review

This is a great tool to use when trying to upload and download files in MicroSD or regular SD. The small compact frame is easy to place away and the covers are great when protecting the usb and usb-c inputs. I had no issues when file transferring and file uploading. I recommend anyone who needs a both ports with usb and usb-c inputs to get this item! The package also was sent right on time with no delay! Like said 100% recommend for anyone who needs a SD transfer tool!

I like the rite parts the first time & thats what i got

I have approximately 20,000 songs on my phone and computer that I wanted to copy to SD cards so I could download them onto my car's hard drive, or play directly from the SD cards. Strangely, my over-the-top technology laden car has 2 SD ports but no USB port. I came across this device and, admittedly, was more than a little skeptical that, at its price, it would be very effective. But, the reviews gave me hope. This thing performed almost flawlessly, whether plugged into my phone or my computer. While not exactly lightning fast, it wasn't unreasonably slow, either. As a guess (I wasn't actually timing it), I would say it filled a 32gb SD card with music files in about 40 minutes. No errors, no corrupted files. The only reason I did not give it 5 stars is that the USB C connector is just a tad too short. As a result, in order to keep a secure connection to my Galaxy Note 8, I had to remove the silicone cover I have on it. No big deal. But, for the same reason, I felt it was better to leave the phone stationary while transferring. Anyway, any doubts about the device's abilities and quality have vanished. Don't let the price mislead you. This works and works well.

Adaptors showed up on time and as advertised. We bought two so we can convert flash drive files to laptop files. All good, decent price. Would order again.

De muy buena calidad y práctico para el manejo de las memorias.

I still use this thing all the time when downloading stuff to my microsd cards and it works without a hitch. I am slightly careful with it, making sure I don't put it in or out the ports recklessly. That's because I can feel the plastic bend slightly if I give it a gripping. But it works great for me still, so I recommend it!

The one port I thought I was getting, and the same port connection that all my phones, tablets, and book readers I have, along with numerous other rechargeable items have, is a micro charging port, instead, it has in addition to the standard USB port an older style and larger port, just bigger than a Micro port. It will not help me in most every case except where I can use a USB port, automatically eliminating my other micro charging items such as phones and tablets which was wht I bought it. If you have all these type ports, and no Micro charging ports, you'll probably love this value! Just be aware of what ports it offers. Hated giving it a 3 but I don't think I'm the only one that thinks that though I may be way off base... If you do have these ports, it's would be a great value and a wonderfully simple to use product.

This does exactly what it is supposed to do, transfer photos from a camera to a computer.

This unit looks and feels good, and is easy enough to use, but was of no value to me because it doesn't not improve performance on older SD and Micro SD cards. In fact, it seemed to be about 20% SLOWER than my old USB 2.0 adapters. I will have to buy faster cards to get the benefit of this product. Also note that the product is also quite WIDE and may not fit into your USB port where space is limited.

It works great and is able to read all the cards that I have.

ARRIVED WITH USB CAP NOT WORKING, EVERYTHING ELSE IS FINE

I bought 3 of these for file transferring. Drive transfers at great data speed.
