UGREEN SD Card Reader USB 3.0 Card Hub Adapter 5Gbps Read 4 Cards Simultaneously CF, CFI, TF, SDXC, SDHC, SD, MMC, Micro SDXC, Micro SD, Micro SDHC, MS, UHS-I (Black)

Worked perfectly out of the box!

It was time to get a card reader separate from the built-in system devices. This card reader has flexibility in what it can accept for cards, it has a decent transfer speed, it works with the M2 Studio, Macbook Pro, Raspberry Pi 4b, Windows 11 and Raspberry Pi Zero 2w without issues and it does not heat up (very slightly warm right after use) to any significant degree. While it may not be the latest and greatest technology for a professional who may need to transfer large amounts of data regularly, it does a great general job for creating bootable cards and transferring files & images to MicroSDs, SDs and others. And the price cannot be beat! Thanks for a great reader.

A representitive from GREEN and I have been in contact. The first person wasn’t understanding me, but the 2nd person’s English is better, Debbie. I sent pictures of the pin that broke. She has informed me that the developer(s) will be checking into the Firmware, but at this time Amazon has a large portion of this item.
It’s very possible that I got 1 bad product, but the Costomer Service has been excellent! If more companies were like this, I think business would have a better reputation like it did 30 years ago. I’ll be keeping watch for newer products by UGREEN. I will admit, that on the outside the device does come across as cheaper, but don’t let that fool you. Other than a non-functional CompactFlash port, it works well. They were cool enough to refund my money and didn’t insist on me returning it to them, the pictures were enough. I Am impressed with the Customer Service. Thanks a lot Debbie, for the Email exchanges. High 5! This review is adjusted because of excellent customer service…and product being looked into for updating.

This product is junk. I use ComfactFlash a lot. Swap them in and out, usually Not any problem at all. This evening as I inserted one the softtware I use didn’t register it. I wondered why. So I pulled it, and inserted the next. Checked same program (not App) again. Nothing, just “Generic Device”. I thought that odd, so I got my Magnififer and Flashlight and suddenly I could see why. The pin on the upper left, 2 from the right, had been pulled WAY up apperently and then shove down crossing or connecting with the pin on the far left (1st from the left). WELLLLLlllll…not a wonder it’s not recogized anymore.
This is something I’ve not encoutered before and should not happen if made well. Sadly, I’d ask for my money back but…I think it’s 30 days into owning and using.. So I’m going to look for another, better base device.
Other than the pin, the Customer Service with some other challengs hasn’t proven very good. Customer service isn’t very good with English and at first I thought I was dealing with a Teenager who uses a Cellphone way too much. Came aross very unprofesional.

The device is still good for all other ports except CompactFlash now. But the “Generic DEVICE” doesn’t pass the info of the Card along very well. UGREEN, I have lowered my star rating because of this experience. Do not buy this!!!

After using this a few times, I have to report that it doesn’t work as well as I’d hoped for. I bought it so I could use 2 different cards at the same time. A CompactFlash and SDCard. The way the device is made, both aren’t always always noticed as seperate. I use this hardware with Emulation software, as well as “per normal” with Windows and Mac. I also use it with other OSes, and all around, it fails with a LOT of small and big files combined. It would really help if the different ports would be called something totally different from each other, I’m sure.

It’s not worth returning for the price. I just won’t use it for heavy loads.

Plug and play, nothing to upload.

What can I say, it seems to be well built, it’s fairly priced, it can read several card formats, and it runs at USB 3.0 speeds. It is very lightweight but the construction is very clean and tight. Worked perfectly to move the pictures off my cameras memory card.

If you have one or more of the formats this thing supports, I would highly recommend this product. Having experience with Ugreens other products, it seems they are long lasting and well made and are pretty good investments.
