1) Slow, confusing and rarely updated (any any updates are just as likely to be a regression as an improvement in my subjective opinion) UI. The browser extension is terrible and up to last year, their hacky password-field-finding javascript slowed down several pages to to point it was unusable. It's still not great.

2) The business model of LastPass worries me. Unlike a 1Password (I tried it for a 3 month trial, don't use them or have any skin in the game for them) charges a lot more than LastPass and in addition to having a more smooth, speedy and performant application, they are charging enough money to feasibly be profitable just storing passwords.

LastPass has has more data breaches than the others (google). It's run by a domain register. In my opinion this influences how the password business is run, leading to a marketing-forward rent extraction password manager vs a good one.
