UGREEN 50706 USB-C +USB 3.0 TF/SD Card Reader

It works out really well with my SD Micro Card in my HP Pavilion Computer. I have also tried it on my iPad Pro 12 and it has worked out really well. The only thing so far that I haven't tried yet is to attach it to my computer AND my iPad AT THE SAME TIME and see how it works. Thing is... I don't really need to do that. It just make things very slightly faster. (Maybe...maybe not.)The product is definitely one that I will purchase again!Thanks for putting two of the Readers into one package. That way, I can do BOTH devices at the same time... without having to connect one to both!Hmm... Just remembered that!Thank you!

I bought this so that I could read and write micro SD cards with a phone that doesn't have a slot for them. The fact that it has a regular USB port makes it very versatile so that it can be used with most laptops and desktops as well.The product looks good though it is a bit longer than I would have preferred. There are pretty much no useful instructions with the product, but it is not hard to figure out. The USB-C and regular USB ports are on either end of the product and are protected by plastic caps. The caps stay on reasonably tight and won't fall off just because you tilt the product from side to side. You need to pull them off deliberately.Inserting a micro-SD card is quite easy and the slot is spring-loaded so that you get a clear indication of when the ... MoreI bought this so that I could read and write micro SD cards with a phone that doesn't have a slot for them.

There are pretty much no useful instructions with the product, but it is not hard to figure out. The USB-C and regular USB ports are on either end of the product and are protected by plastic caps. The caps stay on reasonably tight and won't fall off just because you tilt the product from side to side. You need to pull them off deliberately.Inserting a micro-SD card is quite easy and the slot is spring-loaded so that you get a clear indication of when the card is seated in the slot and when it is ready to be taken out. The regular SD card slot, on the other hand has no such spring loading. In fact, at first I couldn't even figure out which way to insert the card and tried several times with the card upside down to what is required. The simplest way to remember how to insert the cards is to always have their metal pins towards the center of the product and the logos towards the outsides of the product.I tested the ability to read and write SD and micro SD cards both on my laptop and on my cell phone. Everything seems to work fine for a simple test. I did not stress-test it with writes or reads that take a long time. So, I am not sure if the product has a propensity to overheat, etc., when subject to such conditions.The main problem with the product is that the USB-C plug is quite short and the main body of the product is very large. This means that the plug can't be inserted fully into the USB-C port of a phone with any kind of case on it (because the body of the product hits the case and stops before the prong makes full contact inside the port) unless the case has a larger-than-necessary opening for the port or is extremely thin. I had to take the cover off my phone in order to test this product with my cell phone. On an ongoing basis, this is obviously neither straight-forward nor convenient.I don't want the product manufacturer to equip this with an extra long USB-C prong because people trying to insert it all the way into a port might damage the port. But either they could have made the prong graduated so that there is a thinner part between the actual prong and the body of the reader so that it can be used with phones that have protective covers on them. Or they could have added a USB-C to USB-C extension in the package in anticipation of this problem. Either way, neither of these was done. It looks like the designers of this product never actually used it in real-life, and what eventually came out was just an attempt that checks all the boxes, but doesn't work particularly well in practice.Overall, I was deeply disappointed with the product because of this flaw that could have been easily spotted and corrected if the designers had bothered to test it in real-life. I would not recommend it.

I had mine since Oct 2020 and zero issues with it since.Its great for my dashcam (to review old video in the car) which uses a micro sd card.Its easy to move files, pictures and video from my samsung s20 to my laptop & tablet or reverse (usb-c & usb-a connections all in one).I like how you can lock in (secured) the sd card so it will not pop out when you carrying it around.Push it to secured it & push it again to release the sd card.Personally, i always have it with me with my cell phone anywhere i go.Just bough another one just for my laptop at home.Another great ugreen product!!!!The (only) downside, you can easy loose the caps. They are not connect to the device.Great price, outstanding product!

For being able to accommodate USB types A and C while housing SD and MicroSD cards, this is an excellent compact solution for me.Beyond that, the only thing people really need to know about this is the real world transfer speeds, which has averaged 88.4 MB/s on both PCs (with USB 3 ports) I've used it on. This is transferring from an SD card to external hard drives.You can also copy files from both the microSD and SD card slots at the same time, which is super nice for my workflow. This is not the case with all readers.Not sure why more people aren't sharing their transfer speeds as that's the most important data point of any card reader.

I first bought this UGREEN OTG card reader over a year ago, and to this day, I still keep it in my car since it's used for transferring video clips from my dash cam's micro sd card to my Android phone or tablet via USB OTG (and of course, to my PC too).Fast forward to this year, and I was actually in the market for a good but affordable 128gb USB flash drive. Some of the reasonably-priced ones available had terrific read speeds, but very slow write speeds, which was unacceptable to me. And the thumb drives with fast write speeds were just way too expensive. In addition, I was concerned with reviews on how hot some of those thumb drives got.After realizing that I had a spare Samsung Evo Select 128gb microsd card lying around, I decided to just spend the $12 on ... MoreI first bought this UGREEN OTG card reader over a year ago, and to this day, I still keep it in my car since it's used for transferring video clips from my dash cam's micro sd card to my Android phone or tablet via USB OTG (and of course, to my PC too).Fast forward to this year, and I was actually in the market for a good but affordable 128gb USB flash drive.

And the thumb drives with fast write speeds were just way too expensive. In addition, I was concerned with reviews on how hot some of those thumb drives got.After realizing that I had a spare Samsung Evo Select 128gb microsd card lying around, I decided to just spend the $12 on another of these UGREEN OTG card readers and put the unused microsd card to good use, using the combo basically as a flash drive. Using this reader, read and write speeds are close to as advertised for the Samsung card (~90mbps both read and write). It can get warm at times (such as when benchmarking), but not hot. And it's narrow enough that when plugged in to the USB (type A or C) port on my laptop, there is enough space for the USB port beside it.Lastly, it is more handy than your typical flash drive since it is an sd and microsd card reader after all (useful for transferring images from my mirrorless camera since my laptop doesn't have a built-in sd card reader). In addition, this reader has both a USB type A and type C plug (most of the flash drives I was browsing were either only type A or only type C). And finally, the UGREEN has a little lanyard, while the other brands didn't, useful for attaching it to things like a keychain. Overall, glad to own a couple of these.

This is a very nice SD card reader, however, I docked it 1 star because on my iMac the USB port is vertical. What this means is that, when the drive is inserted, the SD card points down and not up which is cumbersome to use in that position. Try inserting an SD upside down! On my attached add-on hard drive, this is even worse because, the vertical USB port will cause the reader to be uspside down and the SD card will be hitting the top of my desk when inserted making it impossible to use unless I raise my drive by 1/2 an inch. The reader works as advertised with no problems (a good thing). In hindsight, I would buy a reader with a flexible cable that would provide more flexibility and ensure that this type of problem does not occur.

I've been using a reader from Anker for a few years. Needed another reader to carry in my backpack. I purchased this one because it was on sale. So far, this thing performs better than my Anker reader. It is detected by my Windows PC promptly, and ejects quickly. Although I did not do any performance tests, it seems to be faster than my Anker in both read and write. The bonus is the USB-C interface, which allows me to use it in my Samsung mobile phone. A couple of other positive things worth mentioning: the microSD slot is actually spring-loaded; the "click" gives the user an indication that the card has been inserted correctly; I also like the slim form of this reader (good for tight/limited space).Don't know how long this thing is going to last, but so far, it ... MoreI've been using a reader from Anker for a few years.

Pros:-Reads 2 cards at the same time (1 must be microSD)-USB-C head is a bonus for compatibility.Cons:-Thick body blocks out neighbor USB-A ports from use without some strain even without a card mounted.-Putting in a full SD card will completely block 1 or 2 USB-A ports right next to it if they're arrayed with the long side of the USB port down.I've not used the USB-C head yet.I regret buying only one Saicoo USB card reader that could read 2 at once and had 2x ports for both SD and microSD. That was back in 2014 and the listing is for a CAC card reader now. It has a short cord to avoid collision with other USB accessories and allows any combination of SD + microSD <= 2 total. It's usable but far from ideal for NAS on my Raspberry Pi.

I love the fact that they used a spring loaded mechanism of the micro SD card. It makes removal of the card very easy as anyone who has tried to remove a friction-based slot knows what a PIA that can be. Also, the aluminum shell made the product feel sturdy, unlike the plastic crap that one usually gets from china.I tested the performance specs using but USB A and USB-C and there is definitely a profound difference so that tells me this is just more than a two connector product with a cheap interface, they truly have a USB-C AND a USB A 3.0 interface.One unexpected pleasant surprise. If you plug in both a Micro SD card using an SD card adapter in one slot and plug a microSD card in the other, the OS recognizes it as two drives.

I'm not sure how many times I might use this feature but what that means is that using one stick, you can easily clone a two Micro SD cards. I tested this on a Raspberry PI 4 using the Raspbian Clone SD utility and it worked.One and only one criticism. This device needs an activity indicator LED and then it would be perfect.

I want to caveats this with my iPad Air has a USB-C port not the lightning port. I was able to easily swap out micro SD and SD cards then plug them into my computer if necessary. Your major cost will be the SD card you get. I used a 1TB with 160mb/s transfer rate so I did not have to have this plugged in forever transferring files. What this does not have is a program that automatically copies and/or syncs your data, but I am okay with that and a little leery (paranoid?) about those programs. I was able to locate any file using Apple’s File app. Pictures required me to select the photos in the photos app, copy them and then when it asked where to copy them I just navigated to the SD card. I like that this is a cheap interface to the memory cards. If lost or broken ... MoreI want to caveats this with my iPad Air has a USB-C port not the lightning port.
