Unreliable
Crashed while copying multiple times on multiple devices. Great idea, not reliable.

Great USB drive.
I needed a USB-C drive for my MacBook. However, I needed something that can connect to both my MacBook and my Windows Machine. My Windows machine is a little older. So, it doesn't support USB-C. With this device, I can use both USB-C & USB 3.1 to get the job done on Both Mac and Win10 machine.

Duo plus 256DB
Used to store music. On playback, it disconnects quite often using the type C USB connection even if you made sure that all members are secure. Not a good combination of you are a DJ.

Slow transfer speed
Uploading an ISO file to a NTFS formated drive over USB-C from a Samsung 960 SSD the speed averaged at 60.9 MB

Disconnects
sustained reads at full speed will over heat the drive and it will disconnect.

Separated usb-c section from rest pf the body
The overal desing looks OK, but there are some issues with it.
I like the ide aof having both usb-a and usb-c in one device, in elegant form factor like this one.
But as already some review mentioned, the device build quality is not that strong. I plugged usb-c connector to laptop (HP elitbeook 735 G6), and apparently this laptop has some tigher tolerances on their usb potrt or what, simply the connection is stronger than in some other devices, and while pulling the flash-stick out, I broke it. The usb-c connector stayed in laptop, and the plastic cover detached from rest of plastic body... (sorry I have no photo).
If I knew this vulnerability, perhpas with more careful pull I could prevent it (or use some tool other tool for help, not just bare hands), however still I consider this rather poor design.
Later on I removed that separated usb-c pasrt from laptop, and glued it to the rest of plastic body with the glue...
With some careful use the flash is still normally usable, but one has to be extra careful, when pulling the flash out of usb-c, especially if it is the one with firmer grip.
Also right from the beginning I was wondering, why Samsung opted for such a strange approach, that the black piece is used as conversion from usb-c to usb-a.
Why instead did't you just use the middle part as fixed body with usb-a on one side, and usb-c on other side, and from sides just use plastic covers.
This would minize the need to move that conversion items, so I would say improve live time of the product overall, and just would be somewhat more natural design in my view..
So long story whort:
I like toe overal design.size/form/look of this product. But is has the issues, see above.
I think if you adapted suggested design, that you have just one middle part with both connectors from each side one type, and then just some plastic covers on both sides, that desig would be somehwat better. Also make sure that connectors can withstand some more aggressive pulling (perhaps make the body internals with some metalic scelet), ant it would be pretty cool product.
Sadly right now it is rather mixed impression.
(I am not evaluating/discussing speed/performance, because that is not that important for me usually. Overal for my occasional use the performance is absolutely acceptable)
