I've been using the UGREEN SD Card Reader USB 3.0 Dual Slot since 2019, and it has been an outstanding device. Its durability is impressive; after years of regular use, it still works fantastically without any issues. The Card Reader has significantly streamlined my workflow and saved me a lot of time. The build quality is solid, and the device feels sturdy and well-made. The dual slot design is incredibly convenient. It's compatible with various card formats, which adds to its versatility and makes it suitable for different devices. Pros: ⚫Great device with long-lasting performance since 2019 ⚫Fast transfer speeds with USB 3.0 ⚫Dual slots for simultaneous reading and writing ⚫Compatible with multiple card formats ⚫Solid build quality and durability Cons: ⚫None that I've experienced Recommendation: Highly recommended for anyone in need of a reliable and efficient SD card reader. It's a worthwhile investment that delivers consistent performance and convenience over the long term.

This SD card reader met my needs exactly. I was looking for a small USB 3.0 to SD card hub that I could modify with a heat sink and fan to keep temperatures low while transferring large files. This fit the bill and worked out better than I had imagined. Before getting this I would see temperatures exceeding 150 degrees Fahrenheit while transferring lots of data to these micro SD cards. I've even had SD cards fail because of heat. They became corrupted and I would have to reformat, and start loading them all over again. We all know these 1TB SanDisk micro SD's are not cheap, so I decided to do something about it. I ordered this reader along with some .5mm Thermal Grizzly Minus Pad, and 1.5mm Thermalright thermal pads. Added a 5 volt "NewHail Replacement Heatsink Cooling Fan" that I found on Amazon also. The results speak for themselves. I soldered into the 5 volt rail on the readers logic board so the fan gets power from the USB. After doing so I positioned the thermal pads on top of the micro SD card slot, and on top of the reader chip to then lay evenly on the bottom of the heat sink. Added hot glue because I can always remove it if need be. If you are unaware, isopropyl alcohol will loosen hot glue and make it easy to remove. I then plugged it in to my PC, and transferred several large 20 gigabyte files. The micro SD card is the hottest point in the pictures from my UNI-T UTi260B thermal camera. I could only get the SD card to heat up to around 102-104 degrees Fahrenheit with large files. Small files it would average around 98.5 degrees F. That is nearly a 50 degree difference!!! A lot of you are going to laugh at this review, but for me this was a needed solution for the issues I was facing loading 1 terabyte micro SD cards. I thank U-Green for making a product that fit my needs exactly.

I use this regularly and it works great after a year and a half. The USB connecting wire is short but thick and sturdy. It holds up well. Sometimes the cards need to be inserted over again because they didn't read the first time. I usually blow a little air in (I use a little old school camera dust cleaner with the air pouch you squeeze so the air shoots through a small tube) just to make sure the contacts aren't dusty. I recommend storing the reader when not in use to avoid that but I sometimes get lazy and dont bother. There are two slots, one for standard sd and one for micro sd cards. I never used both at the same time so I can't say if that's possible or not. The transfer speed is pretty good if the cards are in properly and their contacts are clean. I think the time is between 13. And 17. mb per second. I dont know how that rates against others but that's the best I have personally encountered. I've experienced other card readers whose circuitry gets fouled up fairly quickly and becomes worthless but that hasn't happened yet after a year and a half. I am super careful with all card readers so not to drop them just in case of that internal damage. I don't know how delicate this one is but I assume all card readers are delicate. I once had one last less than a week once. This reader is going strong after 18 months. I suspect it will last as long as I need it.

my only complaint is that the cable is too short and stiff, so it just hangs there flaccid on my desk while plugged into my powered USB hub.

I got this for a 2018 Tesla Model 3 to use 2 memory cards from one USB port. It works ok, but I did need to use a single card reader for the car to use the dashcam format feature. After the card was formatted and usable as a dashcam I changed it to this reader and it continued to work correctly. So this does not allow for formatting, but it does appear to work ok for daily dashcam use. It can read both cards at the same time without issue while I have a phone charger plugged into the other available USB port.
