I love this flash drive, but I expected I would after researching drives for almost an hour (Yeah, that's how I roll; I over-research almost everything I buy.). I wanted a drive that would automatically back up files without me having to drag and drop the ones I thought had been updated. This one surpasses my needs as it syncs/backs up my favorites, the document folders/items I choose, and e-mails, if I so choose. The software is easy to use with a simple interface. No installation needed. The transfer rate seems fast to me, but it's not like I wait until the last minute to download secret spy files before the bad guys catch me. The space is perfect, though I also have a 16GB one. The price was inexpensive. I like the keychain ability, though I don't use it. The only suggestion/flaw is that the cap could be easy to lose...it would be nice if it was a sliding closure. However, I'd still buy this again and won't buy any flash drive unless it has JetFlash software now, something I didn't know I'd love as much as I do. Hope this helps.
