1.) The USB 3.0 connector is very tight and I have had a real struggle fitting it in to several of my devices.
2.) Because of the tightness of the connector the slider/catch that holds the USB head forward is almost
useless and occasionally gives way and allows the head to be pushed back inside the body when being inserted.
So I now have to hold the slider forward with my thumb whenever I'm trying to insert it just in case it's pushed back.
Of course the USB connectors on some devices are upside down so I have to do this from underneath the drive.
It's ironic since some of my older USB drives had sliders that were way too stiff to move back and forth frequently.
So I'm now looking for USB thumb drives that don't have any sliders. They never work well!

Al introducir el usb me salta un error:
"No se puede obtener acceso a H:\.
El medio está protegido contra escritura".
Consultando soluciones y comentarios de otros usuarios, a parte de descubrir que no tiene solución, me he dado cuenta que hay modelos que tienen led de estado, mi unidad no tiene y temo que sea una falsificación.
En fin, ya voy tarde para devolverlo, pero espero que mi comentario sirva de ayuda a otros usuarios con el mismo problema.

People please don't write if you not sure how to get full speed.
First thing you must be sure about usb 3.0 in your system or notebook....
Second think format your usb drive to exfat (by standart it's fat32 or ntfs) . Exfat have no limits on single size file.
Third think if you got true usb 3.0 and right format Exfat. Be sure that in your system controller got correct driver installed - to be true stok driver don't give you full speed.
And yes its hot on full speed 100% . Controller on usb flash gets hot in 2-3 mins but no issue.
Please right useful competent comments.
Good luck fox ;-)

However, yesterday when I was doing a backup the data transfer between my laptop's SSD and this stick suddenly dropped to something like 330KB/sec and the laptop froze. Nothing would work- keyboard, mouse pad - nothing.
I couldn't even do a restart or enter Task Manager to kill any processes. I had to remove the stick and completely power down the laptop.
Restarted the laptop and inserted the USB stick. Immediately, everything went slow as if something was tying up the CPU and although the stick was recognised in Device Manager I couldn't access it. Removed the stick, rebooted and everything was working normal. Gave it one more try and managed to access the stick's properties before it slowed down again. Was astonished to see it was reported as a 64GB when I bought (or thought I bought) a 256GB - see picture.
To avoid any ambiguity I always perform a full virus scan before backing up so I can only conclude the stick has become corrupted
After reading some other reviews on here I can definitely say there is no blue light on this stick and it is marked 256GB when it clearly isn't.
I would not recommend this product.

Inserted into the blue USB slot, it copied 11,967 items (worth 38 GB) from my 8-yr-old laptop onto the memory pen in 1 hour 31 minutes. Idk if this is really bad or reasonable, or if my old laptop is to blame. But it was a one-off big transfer so I'm not too upset.
It does flash blue during file transfer and when browsing files. I'm glad about that, as a reviewer from 2018 said counterfeits don't light up.
It quickly got a bit warm to the touch during the file transfer (not boiling hot tho). And now plugged into my new laptop for just browsing the files, the memory pen feels cool again, maybe a teeensy bit of heat.
It has a security feature where you can drag your files into a password-protected bit if you want to use that.
I spent ages researching which memory pen I should get lol. And I'm happy enough that I went with this one. But maybe I should have paid more for a 400 MB/s speed.
