Nice high-quality flash reader and writer
Style: Adapter
I got this to work with CF (compactflash) cards to be used in my vintage computers like some old PowerBooks from the 90s. This inexpensive reader works really well and is pure plug-and-play on my M3 PowerBook Pro. Performance as far as my CF cards are concerned is respectable -- those old 90s disks held just a few hundred kilobytes each, so hard to give the reader (or the CF card) a speed rating for such small transfers. Suffice it to say I'm really happy with this reader. It's well built and can also work with other modern flash memory cards. Only thing to be aware is it uses the old A type USB, not the current universal C type. Probably a product made a few years ago. Nonetheless, it works well and looks not half bad.

Thoughts and regrets after buying
Style: Adapter
UGREEN SD card reader does the job well for multiple card types, including the CF cards I needed. The build is decent, but yeah, it’s USB-A and a bit bulky with that long cable—so not ideal for on-the-go setups. If you mostly stay at a desk and need a variety of card types, it’s still a pretty solid choice—but for mobile, it’s not quite what I hoped for. That’s not necessarily the fault of the product but it is something that I regret after the purchase. I will knock off one star because it’s only USB-A and I have to use a converter for some of what it connects to. This is 2026, most everything USB-C. Other than that, the device performed just how I needed it to.

A pin broke easily for CompactFlash.
Style: Adapter
2/23/2017 @ 4:03 PM 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. 2/17/2017 7:30 PM. 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.

Reliable Hub That Keeps You Connected
Style: Adapter
This little hub has become a must-have on my desk. It plugs into a USB-A port, and suddenly I’ve got slots for SD, micro-SD, and even extra USB ports—all simultaneously. Transferring files from my camera’s SD card is noticeably faster than my laptop’s built-in reader, and it doesn’t spike in temperature like some cheaper hubs. Everything just works when I plug it in: cards mount instantly, transfer speeds hold steady, and I’m back to sorting photos in a flash. That said, while USB 3.0 speed is respectable, it doesn’t turn your 200 MB/s SD card into a rocket ship—think more “decent commute” than “supersonic.” And even though it’s compact, it can add clutter if you’re juggling cables and dongles already. Still, this hub is dependable, well-built, and worth tossing in your bag if you regularly hop between devices. It’s one of those “just solves stuff” tools that you don’t realize you needed—until you do, and then you actually thank the USB gods.
