    The item took almost 2 weeks to deliver and it showed it being in stock. I suppose it can be blamed on the holiday time period, but other items arrived faster. The flash drive arrived in good condition and I have already put it to use. It works perfectly and connects easily. I have seen a few reviews where the drive had issues in that respect, but in numerous connections, it is fine. I like that the bright red color makes it easy to spot.

    I needed to secure info from my older computer. The drive provided the ability to do that. This time since I was not sure whether the computer was fixable, I gave the drive to the Geek squad to download if that was needed. They did a great job and provided good advice.

    When my car CD player failed and the covid chip shortage made replacements hard to find, I decided to backup my cd collection in music files (mp3, flac etc). On sale for $10, the SanDisk 64GB was the perfect choice. I backed up over a hundred cd's in high quality flac format and still have 22GB left on the flash drive.
