Vansuny 128GB Type C Flash Drive 2 in 1 OTG USB 3.0 + USB C Memory Stick with Keychain Dual Thumb Photo Stick Jump Drive for Android Smartphone, Computers, MacBook, Tablets, PC

This Flash drive will not disappoint! Blazing fast data transfer rates on both USB ends! Very durable & quality construction. Massive 512 Gb storage. Transfer large video files from my desktop to my phone with ease. No heat issues, no data transfer issues. Very pleased with the value & quality!

When a different C Flash drive I had failed to copy a video I had on my pone I purchased this Vansuny C Flash drive and it performed without fail. It copies photos and videos perfectly allowing me to transfer them to my laptop flawlessly. Its claim of 128 GB is accurate. Do know that the USB section is a tight fit so be sure to fully insert it. Also, the drive needs to be formatted so when you first install it in your phone check your settings to fully format it (it takes only a moment) before attempting to copy files. So far this reasonably priced thumb drive is doing everything I have asked of it but as with all my reviews if issues arise I will immediately update this review.

Seems well built and solid so far. Works quickly and transferred almost 6GB from my old flash drive in minutes. Plug and play, and go. My only "problem" is the "hanging design"--a tiny, pinhole-like plastic hole near the cap of the USB-A side. I'm not even sure what dental floss wire you'd legitimately be able to put through there. And, as I saw in other reviews, I'm not sure it would hold up--the plastic seems very flimsy compared to the rest of the product. That said, I didn't buy this so I could attach it to something, so it doesn't affect my user experience necessarily. it just seems pointless and something unnecessary and easy to break off.

My Previous car had a hard disc on which I could load from CD's my entire classical music collection -- over 600 movements. My new electric car did not come with a hard disk, but it came with a connection for this thumb drive. I then was able to load my classical CD collection through my computer to this thumb drive. With 125 GB of memory, it only took about 10% of the memory. I am again a happy camper when I drive around in my EV9 listening to my favorite concert music.

thumb drive worked well. both usb and usb-c

Review Updated: After some tinkering, I was able to get the USB-C working again. Plugging it into a laptop with a USB-aC port seems to have fixed whatever the issue was and the phone can now recognize it. Updating to 3 stars as it's working again, but it is still annoying that it stopped working mysteriously for several days when I needed it. Will need to monitor to see if it happens again.As a regular USB drive, it's fine. The USB side is working as expected. However, the Type C side worked on my phone for about a month no problem. Shortly afterwards, though, it stopped reading it entirely. I specifically bought it for its functionality to transfer files from my computer to the phone and vice versa. Now it only works as a regular USB drive, which for that, I could have bought a much cheaper device if that's all I wanted.Unfortunately, the return policy is 30 days, so I just missed out on the window, and the manufacturer's website does not show any type of warranty policy, so this is wasted money. I'll be looking at another brand to buy a replacement.

Value for money is great, the adapter for your phone is great, the caps on the ends stay on very nicely, and of course the size is great. It's amazing for traveling with larger files, I use it when I travel across the country. It's very sleek and professional. Love it.

I mainly got this because it has both normal USB and USB type C connections. I like that I can get work done on my phone or a computer and save it to the drive instead of having to worry about sending it somewhere. The drive lights up red when a process is in action. The plastic hole to connect a Keychain or lanyard is super tiny and just thin plastic that I'm sure will break over time. I wish that loop was better but other than that I like this and think it's a good value. Also nice it has the covers but I could see them falling off/being lost over time.Edit: I still really like it but as I'd guessed, the little plastic connector ring broke (it took a month & a half). So now I just have to store it in a pocket or something because there's no way to connect it to anything. Kind of a bummer but saw that one coming. It's still a great flash drive though and has been convenient for me. Would still recommend but if being able to connect it to a lanyard or keychain is important to you....well that's not a lasting trait. Also, I wanted to mention because I'm getting a lot of Amazon's "Can you answer this customer's question?" emails about this item....if your phone has a USB-C port then yes it can be used with your phone. I have a Galaxy S22+ that I use it with regularly and have also connected it to an S10e and an A10e without any issues.
