64GB USB Flash Drive, USB-C Ultra High-Speed USB 3.1 Flash Drive with Pen Design, Plug and Play, Portable Memory Stick, Data Storage Drive Compatible with Computer, Laptop, Smartphones

A pen with usb great idea!

Can't ask for more

According to my phone: Product name: USB3.0 Card Reader Device Class: 0 Please provide firmware to change the device class. I'd like my phone to recognize this flash drive's existence so it can actually use it. Thx.

Is not good stuff, I hate my orders , not easily for used on cell phones not good for computer too

The unit works as expected, care must be taken when connecting or disconnecting but it works fine.

Pros: 1) The pen design is stylish IMO. 2) Good build quality. Feels solid, robust, and pleasantly heavy. 3) Is a genuine 256GB drive, not a fake. 4) Has a USB-C port, making it easy to transfer files between your computer and phone. 5) Comes with a video showing how to replace the ink cartridge. Cons: 1) As a pen, the ink quality is mediocre, on par with a disposable BIC or Penmate pen. 2) The ink replacements are proprietary. So once you're out, you're out. Or you may have to contact the company to send you more. 3) Doesn't reach advertised read speed of 150MB/s. In CrystalDiskMark, the performance I got was about 98.5MB/s read and 70.5MB/s write. That's not bad, but it's not as good as advertised. 4) As another reviewer mentioned, the drive does get a bit hot when used. 5) Some EMF interference comes from the drive when transferring files. Don't plug it in next to a Bluetooth or Wifi dongle on your device. If you're looking for a novelty "hidden" USB drive, then I recommend this product. It's a good combination of novelty and practical design. While there are some other USB drives that double as pens, this one is far superior in form and function.

Comes with no instructions, but it was easy to figure out. Great tool, I enjoy it and it writes well I wish I could get blue ink

I was excited to see a USB-C pen drive (literally a drive in a pen, not just a usb flash drive), and while my expectations were modest for this device's performance, I wouldn't say it's "ultra high-speed" as described in the product title. The description promises "read speed of up to 150MB/s and a write speed of up to 50MB/s" but I saw 90.3MB/s read and 35.1MB/s write directly plugged into my Macbook Pro M2's USB-C/Thunderbolt 4 port. with Blackmagic Speed Test. Performance on Windows with Crystal Diskmark Realworld Performance benchmark was slightly better, at 94.77 read and 40.63 write, with 71.51MB/s in 70R/30W mixed benchmark. In a real-world test, copying a number of videos (about 7.18GB across 6 videos), Windows showed the speed in the 30-35MB/s range most of the time, getting up to around 40 from time to time but not consistently. In addition to the USB-C port advertised, there's a female MicroUSB port under the pen's cap. No cable included, and most people won't need it, but it's there. Performance was a lot lower, 35MB/s read, 26MB/s write, 37.08MB/s mixed. Another odd detail is that when I connected the drive to my Macbook, it was recognized as a card reader. As with many novelty drives, if you're writing once and not in a hurry, you'll probably find the read speed to be acceptable for most portable use cases. Watching the videos I copied over went well, just took longer than I'd hoped to write them.

Never worked, returned.
