    Whenever I am in need of more flash drive memory, I always go to Bestbuy.com and look for the Sandisk items on sale. I have never had any issues with any of them that I have purchased through the years. I will buy more of them here when I need them.

    I bought this thumbdrive to carry on my keychain to always have my important files on me that I need daily. The read and write speed are excellent for the price (slower than others that are double the price). To me, it's an acceptable trade off. My only problem with this thumb drive is that since I wanted to carry it on my keychain and the hole where the keychain goes is behind thumb thumb switch to retract the head of the drive so it cannot be fully retracted because it will hit the keychain. If it didn't do this, I would have given it 5 stars.

    I bought this item to use with my Sony VAIO laptop, it does the job just as described. I also bought another one for my brother as a birthday present and he is pretty content with the flash drive. I will recommend it to anyone who has lots of photos and videos piled in laptops. Free that memory up with this flash drive!

    I purchased this at a steep discount during one of the 4 hour online sales I used this to consolidate all other, much smaller sized, flash drives I had lying around. This has helped me free up so many flash drives and SD cards. I have never had a problem with this brand before and hope to never have a problem in the future.

    Great deal on a great product. Purchased this for my grandson for Christmas as he keeps running out of room on his computer for all of the things he wants to save. The daily special enabled me to purchase the 128gb for him at a fantastic price. Have used the SanDisk products for many years and have never had a problem.

    128GB in a drive literally the size of my thumb. Plug right in and go. A little concerned about the plastic construction so I'm hoping it holds up over time.

    Needed a new thumb drive for work and this one did the trick. I usually recycle my thumb drives yearly so this one will do just fine. It's nice because you don't have to worry about losing a thumb drive cap

    I bought this 128GB flashdrive to back up my computer before taking it in for repair. All my docs, all my music, all my photos - downloaded onto 1 flashdrive, and still have lots of room left. Bought it on sale with BestBuy, so it was perfect all around. Definitely worth the $... and the $$ saved!!
