    I got this on sale so admittedly I didn't pay the full price. However, it has functioned perfectly. The only minor annoyance is that the retractable USB plug doesn't always stay retracted when in your pocket or on your key chain, so I'm continuously having to check to makes sure it's secure. However, in all other respects, I'm very pleased with it.

    Does what it should. I’m not going to say anything else about this product. BestBuy ,however, is a very good retailer and I always enjoy my shopping experience with them.

    Good USB at a very low price, I wish the body could be made of metal, I had previous plastic ones (not this brand) broke on me.

    SanDisk continues to provide quality, easy-to-use storage products. My experience with their SSD and SD Card products led me to choose this USB Flash Drive, and I've not been disappointed. I purchased a few of them for both work and home use, and they've all met my high expectations.

    I remember when my entire hard drive was measured in MBs and it cost a fortune. This tiny thing is 128GB. Im old, and this is alot of space in a tiny package for cheap.

    I am using this drive for various projects. The read speed are excellent 50MB/s +, the write speeds work well in short bursts 50MB/s +, but about about 30 secs drop to about USB 2.0 speeds 10-12MB/s. This is due to the budget flash memory. Still an excellent drive.

    I purchased this flash drive to back up my documents, pictures, videos and music from my desktop computer. It worked perfectly for me. It took four hours to write 90 gigs of mostly music to this drive on a 2.0 usb port. That was exactly what I needed and expected, considering the price.
