COASD Memory Card Reader SD OTG Adapter and USB 3.0 Portable for SDXC, SDHC, SD, MMC, RS-MMC, Micro SDXC, Micro SD, Micro SDHC Card and UHS-I Card (Type C)

I used the card reader to transfer about 35G data from my PC to a micro SD card very quick and no problems. Checked the OTG function by plugging it directly to my Galaxy phone to transfer files from a micro SD card to phone, again, no problems. I've tested both the SD and micro SD slots, the USB and micro USB, but not the USB C. So far so good, its a keeper and a handy tool for transferring data between a variety of devices that use SD and Micro SD cards.Great product and highly recommend!

I bought it to use my 3D printer and this works well. It is easy to use micro SDHC and it works well. I like this one. Also, I can use it with my phone because there is C-type connector. I love it!

Basically, I am pleased with this SD Adapter. I purchased THREE of these because:* I need readers for my Micro SD Cards.* I need readers for my full sized SD Cards.* Also I need a OTG USB Plug for my tablets and phone. And also wanted a USB Plug to use for transferring files, pictures etc to my computer.* This read all of my SD cards from 32GB to 64GB.In all above respects, this reader worked very well. Below I list what I like and do not like:LIKE:1 Small unit that reads my Micro cards and large SD cards in ALL of my OTG Capable units.OTG means on the go...these type units fit I to a phone or tablet that has OTG capability. Not all phones and tablets have this so before you purchase this, check to see if your phone or tablet has this.2 Fairly well made. It works and really for the low price....a bargain!3 Pretty pink color.4 When my 64 Micro SD card is inserted, I can use this as a On the Go Flash drive.I tried 32, 64 and 64 SD cards, this reader read all of them. I was impressed.5 Made fairly well...see below.Dislikes:1 The wide bottom on the SMALL USB end. The USB Plug fit but I had to remove my phone's cover, then it worked.2 The top on the SMALL USB side was very difficult to snap on. It took me a few minutes to finagle it but I finally got it on.I have rated this 4 stars because of those two CONS/DISLIKES.

Fantastic product. Bought to watch movies on my home tv that were downloaded on my android. Works flawlessly.Have to say tho, I got lucky. The SD card sticks out the side and JUST fit in the nook on my tv that holds the usb port. Also, you're gonna want to wrap a piece of tape around it to hold the SD card in the stick. If the SD card pops loose, it can dry the card. Lost 2 that way.

I bought this for my boyfriend's game cam cards. The card is a small sd card and it was a pain to try and review the photos on the camera. This card reader made things more easier since I was able to use with my laptop. With plug-n-play, it works perfect.

Reader, per se, works fine as an adapter for a MicroSD card. However, I could not get the USB end into a USB port on my PC. Tried two ports and it just would not go in. Was going to do a return. I remembered I had a 2.0 4 port hub I was not using, pulled it out and, after a good hard (emphasis on hard) push, got this device to go in one of the 4 ports. Since I was not using the hub, I'll just leave this device plugged into it. (The USB end of the hub cable plugged into the PC with no problem in case someone was wondering.)

I needed a way to read SD cards and micro SD cards. I wanted to be able to read them through a standard USB and a micro USB slot. This product does it all. I know. I tested it out as soon as I got the thing. You may think that is one of those phony reviews, but its not. It's not really a hugely complicated thing, but getting it right so that it's convenient and easy takes some user interface engineering. This does all I need and very elegantly. If you need the same capabilities I needed, this is the device for you.

OK, so you know working with portable devices you don't get a lot of space nor open extendable ports on cellphones, tablets etc. So I went on the hunt and I came across this card reader on Amazon. Yessssssssss best thing ever!!! I was able to insert (dependable on my portable devices the various sizes found in Micro and Mini cards) SD cards via the USB port and it showed instantaneously. I was able to load my SD cards with ease. This is a great product and I am so glad I got the pink one because of its bright color I can locate it quickly in a drawer, pocket, bag, or purse. Thank you.
