I use their cloud sync and love it. One of the few subscription services I pay for. I also use the browser extension, which others have pointed out might not be the best, but I think it's better than one to five universal easy to guess passwords I was using before. I have it on Windows, Mac and Android and it syncs seamlessly.

Been using 1P since version 4 or so and syncing with Dropbox. It works really well and I'm quite satisfied with how quickly they resolve issues (especially security related ones)
