I used to be a free user of LastPass and wanted a vault on-the-go. With LastPass the only option was an annual subscription, for an app that I didn't find particularly impressive.

Switching to 1Password was extremely easy. It offered simple instructions on how to import from LastPass and the pricing model (pay once for the piece of software) was a lot more compelling to me. As an added bonus, the app is super well developed and designed. It _just_ works, and works the way you expect it to. 100% satisfied.
