Works Pretty Well (Read & Write Speeds Below)
Works Well but The only Problem i would say with this usb is that it does get hot.

Great!
Incredibly good value and reads quite fast for the price! Also writes in bursts at a decent speed. If you're not writing large files, it's a no brainer. Otherwise, at USB 3.0 speeds it gets quite warm after some time and I'm guessing the plastic build doesn't dissipate heat much. If you plan to write constantly, I would recommend looking at the metal Luxe version which should retain its speeds longer.

Tiny but mighty
This thing is minuscule but certainly packs a punch. No issues plugging in and using, and file transfer through a MacBook Air’s USB-C 4.0 was BLAZING fast (or at least yards faster than I’m used to from my 10-year-old Intel Pentium PC).

Works fine, delivery fast!
Very handy having both a usb and type c port. Has a short installation app for phones but great for that easy access when it has two ports to plug and play. Very compact! So small in fact that I have to clip it with a keychain so it doesn't disappear on me, but that's a compliment!
