This item helped to save me time in looking for some photographs on a short notice for a celebration of life. I needed this product for the SD card to USB. Glad it was a quick delivery.

When I first got this device and plugged it into my computer it displayed two separate drives, an E: and an F:. I was able to put in two cards, 1 TF card and 1 SD card. My computer with Windows 10 easily displayed both drives at once. After 1 hour of use and exchanging different cards however, one of the drives went missing. I thought the device was defective. I then ordered a new device thinking this was broken already? The new device arrived and I had the exact same issues! It only displayed 1 drive even though I had 2 cards in the unit. Come to find out, all I needed to do was go to the computer drive management. Then, all I have to do was right click on one of the SD slots, and ASSIGN A NEW DRIVE letter! I only have to do this with one of the cards but you may have to click on both cards and assign a new drive letter to each one. You can assign any letter except C or D if you have these in your system already. That fixed everything! And I was a happy camper. Now I have two of these units and they both work perfectly fine. Definitely USE THE USB 3 PORT! You can still use USB version 2 ports however, they are much slower when transferring and reading either from the same cards or to transfer onto your computer. When you put it on the USB port 3, (the blue one) that makes a huge difference both for the internal card reading and writing as well as the transfer speeds to the computer. It’s like Turbo! This thing was super cheap and now I have two. Also transferring pictures from your cell phone to this device was super easy and I was able to back up all my pics, music and files. Using 1 card for backup from my cell was a Breeze! Super fast, super sexy, super easy, super cheap this is the way to go! I highly recommend this pup! Remember to assign a drive letter when you’re using it with the computer and two cards at the same time. I was using Windows 10. Once the letter is assigned, you don’t have to assign it over and over. If you just use one card only, you may not have to assign anything. I used both cards at the same time to test it and to make copies of the cards for backup. Using the USB port 3, the copies were way faster. Peace to this crazy world! And get this device!
