    It is a great price but it feels kind of cheap. It will work for what I needed.

    SLOW write speeds

    It's a small form factor. And I think WD/Sandisk is generally more reliable for storage than the competitors. The read speeds on this does get up to 400 mb/s i think, but the write speeds are very slow. Maybe around 20 mb/s. I don't know though. I haven't really measured it. Just seeing what it says when transferring larger sets of files. I don't know why the write speeds are that slow. Is it because of the small form factor and where the technology is right now? Still, they should say that their write speeds are MUCH slower than the read speeds. The way they market it, i think they said that it's transfer speeds up to 400 mb/s. But that's really only the read speeds, not the write speeds. That's misleading.

    Good drive in a fragile body

    Sandisk is a decent manufacturer of memory products. This one is a good price for the amount of memory, but the plastic head (that inserts into the USB connection) is fragile. I doubt this will survive as long as my other drives did.

    Some devices can be too small for general use.

    It seemed to work OK but was very hard to remove from the computer that it was plugged into. If you need a small device for clearance that is seldom removed this will work great. It was a waste of money for me as I lost it after 3 uses!

    This flashdrive is extremely useful as a backup to my laptop. Most of my essential files had been stored here so I can use in different computer that I used and freeing up my hardrive.

    Couldn't get it to stop crying most of the night for the first month. Ended up having to crate it in the laundry room to prevent night accidents. Pretty sure it’s trying to bite off all of my extremities when I walk around the house, but it’s cute, so I’ll keep it.

    Less than ideal for dash cam captures

    This USB dongle does most of what I ask of it, but not quite all. I use it as the dash cam hard drive in my Tesla Model S, and I occasionally get a message on my dash stating that the write speed of this drive isn't high enough to capture all video recordings. I did no research prior to picking it up, so it's my fault that it doesn't work for me, but it still doesn't quite meet my needs.

    It's light weight and all plastic, so if you worry about scratching your shiny new laptop, this one shouldn't do that. Works as expected.
