    I'd give it 0 stars if I could. Used less than five times and it came apart. I already moved all the files to it and now I have no way to get them back.

    I use these to help store my important Blender files and projects as a backup, yknow just in case. Theyve always been easy to use and so long as youre smart about it very easy to keep track of, the bigger the better and this one is a very comfortable size for keeping whatever files I need safe and backed up!

    Bought this for my daughter who is an undergraduate student. She decided to add a fun course in cell phone photography this semester and needed a way to save her photos since something was down. Please don’t judge me on not knowing. She is exceptionally pleased with the amount of space it has and how convenient it is to transport around. She said it fit easily on an extra keychain she had. I was happy to hear she started to use this to store more items she is working on versus her laptop. If she is happy with it then Mama’s is happy! Especially since it cost a decent price and will last her a long time!

    This little flash drive is amazing. It is super fast and accurate. The price is great. It is still hard to believe 1/2 a TB on this little flash drive. With a couple of these you can backup your entire computer or move all of your files to another or new computer. This is the largest storage on a flash drive that I have found within a price range that an ever-day person can afford. I would definitely recommend this drive to anyone.

    I recently got interested in astronomy and bought a Celestron Origin smart telescope that creates loads of files that we amateur astronomers accumulate & process after the observing sessions. These USB drives hold an incredible amount of data. No negative issues with this product.

    Purchased to transfer a backup of my old Macbook Air to the new one I bought. I wasn't able to transfer Mac to Mac because I was trading in my old one to get a discount on the new one. I was recommended this USB since it was the perfect size! I was able to make a backup using it so I could factory reset my old Mac to be able to trade it. Since uploading my backup, I have been using it for picture storage. It was a great purchase for what I needed and an even greater value since I bought it on sale.

    Works great. It is not the fastest drive on the market, but it does exactly what I want as a value priced, utilitarian storage device. I use it when I go on trips as a backup. No problems at all. I have purchased several SanDisk's and they never let me down.

    This is a good little flash drive that has a decent amount of space and wasn't super expensive. It works with Windows 11, and also manages to work with my old Windows 7 computer as well. There are a zillion of these things out there, and there probably isn't much of a difference between them, but this one has worked well for me.
