SD Card Reader, 3 in 1 USB Type C/Micro USB Male Adapter and OTG Function Portable Memory Card Reader for & PC & Laptop & Smart Phones & Tablets

This card reader works perfectly well. I use it in my laptop, which has a Windows OS, and in my Samsung cell phone. No issues whatsoever. I'm a photographer and my photo files are quite large because I shoot in RAW. This reader does not change or delete my files at all. I recommend it.

This works fine. My only issue is with the caps, which are a loose fit over the male USB ports' plastic surrounds.

Does not fit my Note8 with case. (I use a fully enclosed case so I cant just pop it off easily. Gotta have a tool or I'm breaking nails lolWasnt compatible with my husbands Samsung s7. Was purchased to review card from trail cameras at their locations so we do not have to bring the cards home to transfer files/pictures/videos. Took the trip to trail cameras today only to realize it's not compatible with either phone. What some crappy luck lolSo my advice before you purchase. If u have an s7 Galaxy try another brand. If u have waterproof type phone case on other devices, Try another brand that's compatible with cases.

Works at intended. the smaller cap on mine is loose and falls off easy.

I read through many SD card reader descriptions for one that would work with a Kindle Fire HD 10 (seventh generation), and this otg device did the trick simply, quickly, perfectly.

With my cameras using SD cards this is the perfect addition that allows me to view images when on site.

it can't be use in any of my phones, the conception seen to be to big for the phone and can't even set contact it's gabage.

I tried it once as a card reader on my computer and it did not work. I didn't know which way to put the card in, and worried that I would ruin the card and lose all my photos! I tried both ways. There are no instructions included. Now,aa I just got a new phone and it will not work on it.
